WARNING
Applicability: Class B digital devices.
This equipment has been tested and found to comply with the limits for a Class B digital device, pur-
suant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television recep-
tion, which can be determined by turning the equipment off and on, the user is encouraged to try to cor-
rect the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.

WARNING
Applicability: Cameras with one or more batteries.
Only use the correct equipment to remove the electrical power from the battery. If you do not use the
correct equipment, you can decrease the performance or the life cycle of the battery. If you do not use
the correct equipment, an incorrect flow of current to the battery can occur. This can cause the battery
to become hot, or cause an explosion. Injury to persons can occur.
WARNING
Make sure that you read all applicable MSDS (Material Safety Data Sheets) and warning labels on con-
tainers before you use a liquid. The liquids can be dangerous. Injury to persons can occur.
CAUTION
Do not point the infrared camera (with or without the lens cover) at strong energy sources, for example,
devices that cause laser radiation, or the sun. This can have an unwanted effect on the accuracy of the
camera. It can also cause damage to the detector in the camera.
CAUTION
Do not use the camera in temperatures more than +50°C (+122°F), unless other information is specified
in the user documentation or technical data. High temperatures can cause damage to the camera.
CAUTION
Applicability: Cameras with one or more batteries.
Do not attach the batteries directly to a car’s cigarette lighter socket, unless FLIR Systems supplies a
specific adapter to connect the batteries to a cigarette lighter socket. Damage to the batteries can
occur.
CAUTION
Applicability: Cameras with one or more batteries.
Do not connect the positive terminal and the negative terminal of the battery to each other with a metal

8.13 Changing image mode
8.13.1 General
The camera can operate in five different image modes:
•Thermal MSX (Multi Spectral Dynamic Imaging): The camera displays an infrared im-
age where the edges of the objects are enhanced.
•Thermal: The camera displays a fully thermal image.
•Picture-in-picture: The camera displays a digital camera image with a superimposed
infrared image frame.
•Thermal blending: The camera displays a blended image that uses a mix of infrared
pixels and digital photo pixels. The mixing level can be adjusted.
#T559828; r. AK/40423/40423; en-US 21
Operation
8
•Digital camera: The camera displays a digital camera image.
To display a good fusion image (Thermal MSX,Picture-in-picture, and Thermal blending
modes), the camera must make adjustments to compensate for the small difference in
position between the digital camera lens and the infrared lens. To adjust the image accu-
rately, the camera requires the alignment distance (i.e., the distance to the object).
8.13.2 Procedure
Follow this procedure:
1. Push the center of the navigation pad. This displays a toolbar.
2. On the toolbar, select Image mode . This displays a toolbar.
3. On the toolbar, select one of the following:
•Thermal MSX .
•Thermal .
•Picture-in-picture .
•Thermal blending . This displays a dialog box where you can select the mixing
level.
•Digital camera .
4. If you have selected the Thermal MSX,Picture-in-picture, or Thermal blending mode,
also set the distance to the object by doing the following:
• On the Image mode toolbar, select Alignment distance . This displays a dialog
box.
• In the dialog box, select the distance to the object.
8.14 Changing the temperature scale mode
8.14.1 General
The camera can, depending on the camera model, operate in different temperature scale
modes:
•Auto mode: In this mode, the camera is continuously auto-adjusted for the best image
brightness and contrast.
•Lock mode: In this mode, the camera locks the temperature span and the temperature
level.
•Manual mode: This mode allows manual adjustments of the temperature span and
the temperature level.
8.14.2 When to use Lock mode
A typical situation where you would want to use Lock mode is when looking for tempera-
ture anomalies in two items with a similar design or construction.
For example, if you are looking at two cables, where you suspect one is overheated,
working in Lock mode will clearly show that one is overheated. The higher temperature in
that cable would create a lighter color for the higher temperature.
#T559828; r. AK/40423/40423; en-US 22
Operation
8
If you use Auto mode instead, the color for the two items will appear the same.
8.14.3 When to use Manual mode
8.14.3.1 Example 1
Here are two infrared images of a building. In the left image, which is auto-adjusted, the
large temperature span between the clear sky and the heated building makes a correct
analysis difficult. You can analyze the building in more detail if you change the tempera-
ture scale to values close to the temperature of the building.
Automatic Manual
8.14.3.2 Example 2
Here are two infrared images of an isolator in a power line. To make it easier to analyze
the temperature variations in the isolator, the temperature scale in the right image has
been changed to values close to the temperature of the isolator.

mum temperature.
• Push the navigation pad up/down to change the value of the highlighted
temperature.
8.15 Setting the emissivity as a surface
property
8.15.1 General
To measure temperatures accurately, the camera must know what kind of surface you
are measuring. You can choose between the following surface properties:
•Matt.
•Semi-matt.
•Semi-glossy.
For more information about emissivity, see section 16 Thermographic measurement
techniques, page 69.

8.16 Setting the emissivity as a custom
material
8.16.1 General
Instead of specifying a surface property as matt, semi-matt or semi-glossy, you can spec-
ify a custom material from a list of materials.
For more information about emissivity, see section 16 Thermographic measurement
techniques, page 69.
8.16.2 Procedure
Follow this procedure:
1. Push the center of the navigation pad. This displays a toolbar.

8.17 Changing the emissivity as a custom
value
8.17.1 General
For very precise measurements, you may need to set the emissivity, instead of selecting
a surface property or a custom material. You also need to understand how emissivity and
reflectivity affect measurements, rather than just simply selecting a surface property.
Emissivity is a property that indicates how much radiation originates from an object as
opposed to being reflected by it. A lower value indicates that a larger proportion is being
reflected, while a high value indicates that a lower proportion is being reflected.
Polished stainless steel, for example, has an emissivity of 0.14, while a structured PVC
floor typically has an emissivity of 0.93.
For more information about emissivity, see section 16 Thermographic measurement
techniques, page 69.

a custom value.
8.18 Changing the reflected apparent
temperature
8.18.1 General
This parameter is used to compensate for the radiation reflected by the object. If the
emissivity is low and the object temperature significantly different from that of the re-
flected temperature, it will be important to set and compensate for the reflected apparent
temperature correctly.
For more information about reflected apparent temperature, see section 16 Thermo-
graphic measurement techniques, page 69.

8.20 Performing a non-uniformity correction
(NUC)
8.20.1 What is a non-uniformity correction?
A non-uniformity correction is an image correction carried out by the camera software to
compensate for different sensitivities of detector elements and other optical and geomet-
rical disturbances1.
8.20.2 When to perform a non-uniformity correction?
The non-uniformity correction process should be carried out whenever the output image
becomes spatially noisy. The output can become spatially noisy when the ambient tem-
perature changes (such as from day to night operation, and vice versa).
8.20.3 Procedure
To perform a non-uniformity correction, push and hold the Image archive button for
more than 2 seconds.
8.21 Configuring Wi-Fi

General description
The FLIR Ex series cameras are point-and-shoot infrared cameras that give you access to the infrared
world. A FLIR Ex series camera is an affordable replacement for an infrared thermometer, providing a
thermal image with temperature information in every pixel. The new MSX and visual formats make the
cameras incomparably easy to use.
The FLIR Ex series cameras are user-friendly, compact, and rugged, for use in harsh environments.
The wide field of view makes them the perfect choice for building applications.
Benefits:
• Easy to use: The FLIR Ex series cameras are fully automatic and focus-free with an intuitive inter-
face for simple measurements in thermal, visual, or MSX mode.
• Compact and rugged: The FLIR Ex series cameras’ low weight of 0.575 kg and the accessory belt
pouch make them easy to bring along at all times. Their rugged design can withstand a 2 m drop
test, and ensures reliability, even in harsh environments.
• Ground breaking affordability: The FLIR Ex series cameras are the most affordable infrared cameras
on the market.

13.1 Moisture & water damage
13.1.1 General
It is often possible to detect moisture and water damage in a house by using an infrared
camera. This is partly because the damaged area has a different heat conduction prop-
erty and partly because it has a different thermal capacity to store heat than the sur-
rounding material.
Many factors can come into play as to how moisture or water damage will appear in an
infrared image.
For example, heating and cooling of these parts takes place at different rates depending
on the material and the time of day. For this reason, it is important that other methods are
used as well to check for moisture or water damage.
13.1.2 Figure
The image below shows extensive water damage on an external wall where the water
has penetrated the outer facing because of an incorrectly installed window ledge.
13.2 Faulty contact in socket
13.2.1 General
Depending on the type of connection a socket has, an improperly connected wire can re-
sult in local temperature increase. This temperature increase is caused by the reduced
contact area between the connection point of the incoming wire and the socket , and can
result in an electrical fire.
A socket’s construction may differ dramatically from one manufacturer to another. For
this reason, different faults in a socket can lead to the same typical appearance in an in-
frared image.
Local temperature increase can also result from improper contact between wire and
socket, or from difference in load.
13.2.2 Figure
The image below shows a connection of a cable to a socket where improper contact in
the connection has resulted in local temperature increase.

Application examples13
13.3 Oxidized socket
13.3.1 General
Depending on the type of socket and the environment in which the socket is installed, ox-
ides may occur on the socket's contact surfaces. These oxides can lead to locally in-
creased resistance when the socket is loaded, which can be seen in an infrared image
as local temperature increase.
A socket’s construction may differ dramatically from one manufacturer to another. For
this reason, different faults in a socket can lead to the same typical appearance in an in-
frared image.
Local temperature increase can also result from improper contact between a wire and
socket, or from difference in load.
13.3.2 Figure
The image below shows a series of fuses where one fuse has a raised temperature on
the contact surfaces against the fuse holder. Because of the fuse holder’s blank metal,
the temperature increase is not visible there, while it is visible on the fuse’s ceramic
material.

Application examples13
13.4 Insulation deficiencies
13.4.1 General
Insulation deficiencies may result from insulation losing volume over the course of time
and thereby not entirely filling the cavity in a frame wall.
An infrared camera allows you to see these insulation deficiencies because they either
have a different heat conduction property than sections with correctly installed insulation,
and/or show the area where air is penetrating the frame of the building.
When you are inspecting a building, the temperature difference between the inside and
outside should be at least 10°C (18°F). Studs, water pipes, concrete columns, and simi-
lar components may resemble an insulation deficiency in an infrared image. Minor differ-
ences may also occur naturally.
13.4.2 Figure
In the image below, insulation in the roof framing is lacking. Due to the absence of insula-
tion, air has forced its way into the roof structure, which thus takes on a different charac-
teristic appearance in the infrared image.
13.5 Draft
13.5.1 General
Draft can be found under baseboards, around door and window casings, and above ceil-
ing trim. This type of draft is often possible to see with an infrared camera, as a cooler
airstream cools down the surrounding surface.
When you are investigating draft in a house, there should be sub-atmospheric pressure
in the house. Close all doors, windows, and ventilation ducts, and allow the kitchen fan
to run for a while before you take the infrared images.
An infrared image of draft often shows a typical stream pattern. You can see this stream
pattern clearly in the picture below.
Also keep in mind that drafts can be concealed by heat from floor heating circuits.
13.5.2 Figure
The image below shows a ceiling hatch where faulty installation has resulted in a strong
draft.

16.1 Introduction
An infrared camera measures and images the emitted infrared radiation from an object.
The fact that radiation is a function of object surface temperature makes it possible for
the camera to calculate and display this temperature.
However, the radiation measured by the camera does not only depend on the tempera-
ture of the object but is also a function of the emissivity. Radiation also originates from
the surroundings and is reflected in the object. The radiation from the object and the re-
flected radiation will also be influenced by the absorption of the atmosphere.
To measure temperature accurately, it is therefore necessary to compensate for the ef-
fects of a number of different radiation sources. This is done on-line automatically by the
camera. The following object parameters must, however, be supplied for the camera:
• The emissivity of the object
• The reflected apparent temperature
• The distance between the object and the camera
• The relative humidity
• Temperature of the atmosphere
16.2 Emissivity
The most important object parameter to set correctly is the emissivity which, in short, is a
measure of how much radiation is emitted from the object, compared to that from a per-
fect blackbody of the same temperature.
Normally, object materials and surface treatments exhibit emissivity ranging from approx-
imately 0.1 to 0.95. A highly polished (mirror) surface falls below 0.1, while an oxidized
or painted surface has a higher emissivity. Oil-based paint, regardless of color in the visi-
ble spectrum, has an emissivity over 0.9 in the infrared. Human skin exhibits an emissiv-
ity 0.97 to 0.98.
Non-oxidized metals represent an extreme case of perfect opacity and high reflexivity,
which does not vary greatly with wavelength. Consequently, the emissivity of metals is
low – only increasing with temperature. For non-metals, emissivity tends to be high, and
decreases with temperature.
16.2.1 Finding the emissivity of a sample
16.2.1.1 Step 1: Determining reflected apparent temperature
Use one of the following two methods to determine reflected apparent temperature:
#T559828; r. AK/40423/40423; en-US 69
Thermographic measurement techniques16
16.2.1.1.1 Method 1: Direct method
Follow this procedure:
1. Look for possible reflection sources, considering that the incident angle = reflection
angle (a = b).
Figure 16.1 1 = Reflection source
2. If the reflection source is a spot source, modify the source by obstructing it using a
piece if cardboard.
Figure 16.2 1 = Reflection source
#T559828; r. AK/40423/40423; en-US 70
Thermographic measurement techniques16
3. Measure the radiation intensity (= apparent temperature) from the reflection source
using the following settings:
• Emissivity: 1.0
• Dobj: 0
You can measure the radiation intensity using one of the following two methods:
Figure 16.3 1 = Reflection source Figure 16.4 1 = Reflection source
You can not use a thermocouple to measure reflected apparent temperature, because a
thermocouple measures temperature, but apparent temperatrure is radiation intensity.
16.2.1.1.2 Method 2: Reflector method
Follow this procedure:
1. Crumble up a large piece of aluminum foil.
2. Uncrumble the aluminum foil and attach it to a piece of cardboard of the same size.
3. Put the piece of cardboard in front of the object you want to measure. Make sure that
the side with aluminum foil points to the camera.
4. Set the emissivity to 1.0.
#T559828; r. AK/40423/40423; en-US 71
Thermographic measurement techniques16
5. Measure the apparent temperature of the aluminum foil and write it down. The foil is
considered a perfect reflector, so its apparent temperature equals the reflected appa-
rent temperature from the surroundings.
Figure 16.5 Measuring the apparent temperature of the aluminum foil.
16.2.1.2 Step 2: Determining the emissivity
Follow this procedure:
1. Select a place to put the sample.
2. Determine and set reflected apparent temperature according to the previous
procedure.
3. Put a piece of electrical tape with known high emissivity on the sample.
4. Heat the sample at least 20 K above room temperature. Heating must be reasonably
even.
5. Focus and auto-adjust the camera, and freeze the image.
6. Adjust Level and Span for best image brightness and contrast.
7. Set emissivity to that of the tape (usually 0.97).
8. Measure the temperature of the tape using one of the following measurement
functions:
•Isotherm (helps you to determine both the temperature and how evenly you have
heated the sample)
•Spot (simpler)
•Box Avg (good for surfaces with varying emissivity).
9. Write down the temperature.
10. Move your measurement function to the sample surface.
11. Change the emissivity setting until you read the same temperature as your previous
measurement.
12. Write down the emissivity.
Note
• Avoid forced convection
• Look for a thermally stable surrounding that will not generate spot reflections
• Use high quality tape that you know is not transparent, and has a high emissivity you
are certain of
• This method assumes that the temperature of your tape and the sample surface are
the same. If they are not, your emissivity measurement will be wrong.

Thermographic measurement techniques16
16.3 Reflected apparent temperature
This parameter is used to compensate for the radiation reflected in the object. If the
emissivity is low and the object temperature relatively far from that of the reflected it will
be important to set and compensate for the reflected apparent temperature correctly.
16.4 Distance
The distance is the distance between the object and the front lens of the camera. This
parameter is used to compensate for the following two facts:
• That radiation from the target is absorbed by the atmosphere between the object and
the camera.
• That radiation from the atmosphere itself is detected by the camera.
16.5 Relative humidity
The camera can also compensate for the fact that the transmittance is also dependent
on the relative humidity of the atmosphere. To do this set the relative humidity to the cor-
rect value. For short distances and normal humidity the relative humidity can normally be
left at a default value of 50%.
16.6 Other parameters
In addition, some cameras and analysis programs from FLIR Systems allow you to com-
pensate for the following parameters:
• Atmospheric temperature – i.e. the temperature of the atmosphere between the cam-
era and the target
• External optics temperature – i.e. the temperature of any external lenses or windows
used in front of the camera
• External optics transmittance – i.e. the transmission of any external lenses or windows
used in front of the camera

History of infrared technology
17
Before the year 1800, the existence of the infrared portion of the electromagnetic spec-
trum wasn't even suspected. The original significance of the infrared spectrum, or simply
‘the infrared’ as it is often called, as a form of heat radiation is perhaps less obvious to-
day than it was at the time of its discovery by Herschel in 1800.
Figure 17.1 Sir William Herschel (1738–1822)
The discovery was made accidentally during the search for a new optical material. Sir
William Herschel – Royal Astronomer to King George III of England, and already famous
for his discovery of the planet Uranus – was searching for an optical filter material to re-
duce the brightness of the sun’s image in telescopes during solar observations. While
testing different samples of colored glass which gave similar reductions in brightness he
was intrigued to find that some of the samples passed very little of the sun’s heat, while
others passed so much heat that he risked eye damage after only a few seconds’
observation.
Herschel was soon convinced of the necessity of setting up a systematic experiment,
with the objective of finding a single material that would give the desired reduction in
brightness as well as the maximum reduction in heat. He began the experiment by ac-
tually repeating Newton’s prism experiment, but looking for the heating effect rather than
the visual distribution of intensity in the spectrum. He first blackened the bulb of a sensi-
tive mercury-in-glass thermometer with ink, and with this as his radiation detector he pro-
ceeded to test the heating effect of the various colors of the spectrum formed on the top
of a table by passing sunlight through a glass prism. Other thermometers, placed outside
the sun’s rays, served as controls.
As the blackened thermometer was moved slowly along the colors of the spectrum, the
temperature readings showed a steady increase from the violet end to the red end. This
was not entirely unexpected, since the Italian researcher, Landriani, in a similar experi-
ment in 1777 had observed much the same effect. It was Herschel, however, who was
the first to recognize that there must be a point where the heating effect reaches a maxi-
mum, and that measurements confined to the visible portion of the spectrum failed to lo-
cate this point.
Figure 17.2 Marsilio Landriani (1746–1815)
Moving the thermometer into the dark region beyond the red end of the spectrum, Her-
schel confirmed that the heating continued to increase. The maximum point, when he
found it, lay well beyond the red end – in what is known today as the ‘infrared
wavelengths’.
#T559828; r. AK/40423/40423; en-US 74
History of infrared technology
17
When Herschel revealed his discovery, he referred to this new portion of the electromag-
netic spectrum as the ‘thermometrical spectrum’. The radiation itself he sometimes re-
ferred to as ‘dark heat’, or simply ‘the invisible rays’. Ironically, and contrary to popular
opinion, it wasn't Herschel who originated the term ‘infrared’. The word only began to ap-
pear in print around 75 years later, and it is still unclear who should receive credit as the
originator.
Herschel’s use of glass in the prism of his original experiment led to some early contro-
versies with his contemporaries about the actual existence of the infrared wavelengths.
Different investigators, in attempting to confirm his work, used various types of glass in-
discriminately, having different transparencies in the infrared. Through his later experi-
ments, Herschel was aware of the limited transparency of glass to the newly-discovered
thermal radiation, and he was forced to conclude that optics for the infrared would prob-
ably be doomed to the use of reflective elements exclusively (i.e. plane and curved mir-
rors). Fortunately, this proved to be true only until 1830, when the Italian investigator,
Melloni, made his great discovery that naturally occurring rock salt (NaCl) – which was
available in large enough natural crystals to be made into lenses and prisms – is remark-
ably transparent to the infrared. The result was that rock salt became the principal infra-
red optical material, and remained so for the next hundred years, until the art of synthetic
crystal growing was mastered in the 1930’s.
Figure 17.3 Macedonio Melloni (1798–1854)
Thermometers, as radiation detectors, remained unchallenged until 1829, the year Nobili
invented the thermocouple. (Herschel’s own thermometer could be read to 0.2 °C
(0.036 °F), and later models were able to be read to 0.05 °C (0.09 °F)). Then a break-
through occurred; Melloni connected a number of thermocouples in series to form the
first thermopile. The new device was at least 40 times as sensitive as the best thermome-
ter of the day for detecting heat radiation – capable of detecting the heat from a person
standing three meters away.
The first so-called ‘heat-picture’ became possible in 1840, the result of work by Sir John
Herschel, son of the discoverer of the infrared and a famous astronomer in his own right.
Based upon the differential evaporation of a thin film of oil when exposed to a heat pat-
tern focused upon it, the thermal image could be seen by reflected light where the inter-
ference effects of the oil film made the image visible to the eye. Sir John also managed
to obtain a primitive record of the thermal image on paper, which he called a
‘thermograph’.

Figure 17.4 Samuel P. Langley (1834–1906)
The improvement of infrared-detector sensitivity progressed slowly. Another major break-
through, made by Langley in 1880, was the invention of the bolometer. This consisted of
a thin blackened strip of platinum connected in one arm of a Wheatstone bridge circuit
upon which the infrared radiation was focused and to which a sensitive galvanometer re-
sponded. This instrument is said to have been able to detect the heat from a cow at a
distance of 400 meters.
An English scientist, Sir James Dewar, first introduced the use of liquefied gases as cool-
ing agents (such as liquid nitrogen with a temperature of -196 °C (-320.8 °F)) in low tem-
perature research. In 1892 he invented a unique vacuum insulating container in which it
is possible to store liquefied gases for entire days. The common ‘thermos bottle’, used
for storing hot and cold drinks, is based upon his invention.
Between the years 1900 and 1920, the inventors of the world ‘discovered’ the infrared.
Many patents were issued for devices to detect personnel, artillery, aircraft, ships – and
even icebergs. The first operating systems, in the modern sense, began to be developed
during the 1914–18 war, when both sides had research programs devoted to the military
exploitation of the infrared. These programs included experimental systems for enemy
intrusion/detection, remote temperature sensing, secure communications, and ‘flying tor-
pedo’ guidance. An infrared search system tested during this period was able to detect
an approaching airplane at a distance of 1.5 km (0.94 miles), or a person more than 300
meters (984 ft.) away.
The most sensitive systems up to this time were all based upon variations of the bolome-
ter idea, but the period between the two wars saw the development of two revolutionary
new infrared detectors: the image converter and the photon detector. At first, the image
converter received the greatest attention by the military, because it enabled an observer
for the first time in history to literally ‘see in the dark’. However, the sensitivity of the im-
age converter was limited to the near infrared wavelengths, and the most interesting mili-
tary targets (i.e. enemy soldiers) had to be illuminated by infrared search beams. Since
this involved the risk of giving away the observer’s position to a similarly-equipped enemy
observer, it is understandable that military interest in the image converter eventually
faded.
The tactical military disadvantages of so-called 'active’ (i.e. search beam-equipped) ther-
mal imaging systems provided impetus following the 1939–45 war for extensive secret
military infrared-research programs into the possibilities of developing ‘passive’ (no
search beam) systems around the extremely sensitive photon detector. During this peri-
od, military secrecy regulations completely prevented disclosure of the status of infrared-
imaging technology. This secrecy only began to be lifted in the middle of the 1950’s, and
from that time adequate thermal-imaging devices finally began to be available to civilian
science and industry.

18.1 Introduction
The subjects of infrared radiation and the related technique of thermography are still new
to many who will use an infrared camera. In this section the theory behind thermography
will be given.
18.2 The electromagnetic spectrum
The electromagnetic spectrum is divided arbitrarily into a number of wavelength regions,
called bands, distinguished by the methods used to produce and detect the radiation.
There is no fundamental difference between radiation in the different bands of the elec-
tromagnetic spectrum. They are all governed by the same laws and the only differences
are those due to differences in wavelength.
Figure 18.1 The electromagnetic spectrum. 1: X-ray; 2: UV; 3: Visible; 4: IR; 5: Microwaves; 6:
Radiowaves.
Thermography makes use of the infrared spectral band. At the short-wavelength end the
boundary lies at the limit of visual perception, in the deep red. At the long-wavelength
end it merges with the microwave radio wavelengths, in the millimeter range.
The infrared band is often further subdivided into four smaller bands, the boundaries of
which are also arbitrarily chosen. They include: the near infrared (0.75–3 μm), the middle
infrared (3–6 μm), the far infrared (6–15 μm) and the extreme infrared (15–100 μm).
Although the wavelengths are given in μm (micrometers), other units are often still used
to measure wavelength in this spectral region, e.g. nanometer (nm) and Ångström (Å).
The relationships between the different wavelength measurements is:
18.3 Blackbody radiation
A blackbody is defined as an object which absorbs all radiation that impinges on it at any
wavelength. The apparent misnomer black relating to an object emitting radiation is ex-
plained by Kirchhoff’s Law (after Gustav Robert Kirchhoff, 1824–1887), which states that
a body capable of absorbing all radiation at any wavelength is equally capable in the
emission of radiation.

Figure 18.2 Gustav Robert Kirchhoff (1824–1887)
The construction of a blackbody source is, in principle, very simple. The radiation charac-
teristics of an aperture in an isotherm cavity made of an opaque absorbing material rep-
resents almost exactly the properties of a blackbody. A practical application of the
principle to the construction of a perfect absorber of radiation consists of a box that is
light tight except for an aperture in one of the sides. Any radiation which then enters the
hole is scattered and absorbed by repeated reflections so only an infinitesimal fraction
can possibly escape. The blackness which is obtained at the aperture is nearly equal to
a blackbody and almost perfect for all wavelengths.
By providing such an isothermal cavity with a suitable heater it becomes what is termed
acavity radiator. An isothermal cavity heated to a uniform temperature generates black-
body radiation, the characteristics of which are determined solely by the temperature of
the cavity. Such cavity radiators are commonly used as sources of radiation in tempera-
ture reference standards in the laboratory for calibrating thermographic instruments,
such as a FLIR Systems camera for example.
If the temperature of blackbody radiation increases to more than 525°C (977°F), the
source begins to be visible so that it appears to the eye no longer black. This is the incipi-
ent red heat temperature of the radiator, which then becomes orange or yellow as the
temperature increases further. In fact, the definition of the so-called color temperature of
an object is the temperature to which a blackbody would have to be heated to have the
same appearance.
Now consider three expressions that describe the radiation emitted from a blackbody.
18.3.1 Planck’s law
Figure 18.3 Max Planck (1858–1947)
Max Planck (1858–1947) was able to describe the spectral distribution of the radiation
from a blackbody by means of the following formula:

18
where:
Wλb Blackbody spectral radiant emittance at wavelength λ.
cVelocity of light = 3 × 108m/s
h Planck’s constant = 6.6 × 10-34 Joule sec.
kBoltzmann’s constant = 1.4 × 10-23 Joule/K.
T Absolute temperature (K) of a blackbody.
λ Wavelength (μm).
Note The factor 10-6 is used since spectral emittance in the curves is expressed in
Watt/m2, μm.
Planck’s formula, when plotted graphically for various temperatures, produces a family of
curves. Following any particular Planck curve, the spectral emittance is zero at λ = 0,
then increases rapidly to a maximum at a wavelength λmax and after passing it ap-
proaches zero again at very long wavelengths. The higher the temperature, the shorter
the wavelength at which maximum occurs.
Figure 18.4 Blackbody spectral radiant emittance according to Planck’s law, plotted for various absolute
temperatures. 1: Spectral radiant emittance (W/cm2× 103(μm)); 2: Wavelength (μm)
18.3.2 Wien’s displacement law
By differentiating Planck’s formula with respect to λ, and finding the maximum, we have:
This is Wien’s formula (after Wilhelm Wien, 1864–1928), which expresses mathemati-
cally the common observation that colors vary from red to orange or yellow as the tem-
perature of a thermal radiator increases. The wavelength of the color is the same as the
wavelength calculated for λmax. A good approximation of the value of λmax for a given
blackbody temperature is obtained by applying the rule-of-thumb 3 000/T μm. Thus, a
very hot star such as Sirius (11 000 K), emitting bluish-white light, radiates with the peak
of spectral radiant emittance occurring within the invisible ultraviolet spectrum, at wave-
length 0.27 μm.

Figure 18.5 Wilhelm Wien (1864–1928)
The sun (approx. 6 000 K) emits yellow light, peaking at about 0.5 μm in the middle of
the visible light spectrum.
At room temperature (300 K) the peak of radiant emittance lies at 9.7 μm, in the far infra-
red, while at the temperature of liquid nitrogen (77 K) the maximum of the almost insignif-
icant amount of radiant emittance occurs at 38 μm, in the extreme infrared wavelengths.

the locus of maximum radiant emittance at each temperature as described by Wien's displacement law. 1:
Spectral radiant emittance (W/cm2(μm)); 2: Wavelength (μm).
18.3.3 Stefan-Boltzmann's law
By integrating Planck’s formula from λ = 0 to λ = ∞, we obtain the total radiant emittance
(Wb) of a blackbody:
This is the Stefan-Boltzmann formula (after Josef Stefan, 1835–1893, and Ludwig Boltz-
mann, 1844–1906), which states that the total emissive power of a blackbody is propor-
tional to the fourth power of its absolute temperature. Graphically, Wbrepresents the
area below the Planck curve for a particular temperature. It can be shown that the radiant
emittance in the interval λ = 0 to λmax is only 25% of the total, which represents about the
amount of the sun’s radiation which lies inside the visible light spectrum.

Figure 18.7 Josef Stefan (1835–1893), and Ludwig Boltzmann (1844–1906)
Using the Stefan-Boltzmann formula to calculate the power radiated by the human body,
at a temperature of 300 K and an external surface area of approx. 2 m2, we obtain 1 kW.
This power loss could not be sustained if it were not for the compensating absorption of
radiation from surrounding surfaces, at room temperatures which do not vary too drasti-
cally from the temperature of the body – or, of course, the addition of clothing.
18.3.4 Non-blackbody emitters
So far, only blackbody radiators and blackbody radiation have been discussed. However,
real objects almost never comply with these laws over an extended wavelength region –
although they may approach the blackbody behavior in certain spectral intervals. For ex-
ample, a certain type of white paint may appear perfectly white in the visible light spec-
trum, but becomes distinctly gray at about 2 μm, and beyond 3 μm it is almost black.
There are three processes which can occur that prevent a real object from acting like a
blackbody: a fraction of the incident radiation α may be absorbed, a fraction ρ may be re-
flected, and a fraction τ may be transmitted. Since all of these factors are more or less
wavelength dependent, the subscript λ is used to imply the spectral dependence of their
definitions. Thus:
• The spectral absorptance αλ= the ratio of the spectral radiant power absorbed by an
object to that incident upon it.
• The spectral reflectance ρλ= the ratio of the spectral radiant power reflected by an ob-
ject to that incident upon it.
• The spectral transmittance τλ= the ratio of the spectral radiant power transmitted
through an object to that incident upon it.
The sum of these three factors must always add up to the whole at any wavelength, so
we have the relation:
For opaque materials τλ= 0 and the relation simplifies to:
Another factor, called the emissivity, is required to describe the fraction ε of the radiant
emittance of a blackbody produced by an object at a specific temperature. Thus, we
have the definition:
The spectral emissivity ελ= the ratio of the spectral radiant power from an object to that
from a blackbody at the same temperature and wavelength.
Expressed mathematically, this can be written as the ratio of the spectral emittance of
the object to that of a blackbody as follows:
Generally speaking, there are three types of radiation source, distinguished by the ways
in which the spectral emittance of each varies with wavelength.
• A blackbody, for which ελ= ε = 1
• A graybody, for which ελ= ε = constant less than 1
#T559828; r. AK/40423/40423; en-US 81
Theory of thermography
18
• A selective radiator, for which ε varies with wavelength
According to Kirchhoff’s law, for any material the spectral emissivity and spectral absorp-
tance of a body are equal at any specified temperature and wavelength. That is:
From this we obtain, for an opaque material (since αλ+ ρλ= 1):
For highly polished materials ελapproaches zero, so that for a perfectly reflecting materi-
al (i.e. a perfect mirror) we have:
For a graybody radiator, the Stefan-Boltzmann formula becomes:
This states that the total emissive power of a graybody is the same as a blackbody at the
same temperature reduced in proportion to the value of ε from the graybody.

18.4 Infrared semi-transparent materials
Consider now a non-metallic, semi-transparent body – let us say, in the form of a thick flat
plate of plastic material. When the plate is heated, radiation generated within its volume
must work its way toward the surfaces through the material in which it is partially ab-
sorbed. Moreover, when it arrives at the surface, some of it is reflected back into the inte-
rior. The back-reflected radiation is again partially absorbed, but some of it arrives at the
other surface, through which most of it escapes; part of it is reflected back again.
Although the progressive reflections become weaker and weaker they must all be added
up when the total emittance of the plate is sought. When the resulting geometrical series
is summed, the effective emissivity of a semi-transparent plate is obtained as:
When the plate becomes opaque this formula is reduced to the single formula:
This last relation is a particularly convenient one, because it is often easier to measure
reflectance than to measure emissivity directly.

The measurement formula
19
As already mentioned, when viewing an object, the camera receives radiation not only
from the object itself. It also collects radiation from the surroundings reflected via the ob-
ject surface. Both these radiation contributions become attenuated to some extent by the
atmosphere in the measurement path. To this comes a third radiation contribution from
the atmosphere itself.
This description of the measurement situation, as illustrated in the figure below, is so far
a fairly true description of the real conditions. What has been neglected could for in-
stance be sun light scattering in the atmosphere or stray radiation from intense radiation
sources outside the field of view. Such disturbances are difficult to quantify, however, in
most cases they are fortunately small enough to be neglected. In case they are not negli-
gible, the measurement configuration is likely to be such that the risk for disturbance is
obvious, at least to a trained operator. It is then his responsibility to modify the measure-
ment situation to avoid the disturbance e.g. by changing the viewing direction, shielding
off intense radiation sources etc.
Accepting the description above, we can use the figure below to derive a formula for the
calculation of the object temperature from the calibrated camera output.
Figure 19.1 A schematic representation of the general thermographic measurement situation.1: Sur-
roundings; 2: Object; 3: Atmosphere; 4: Camera
Assume that the received radiation power W from a blackbody source of temperature
Tsource on short distance generates a camera output signal Usource that is proportional to
the power input (power linear camera). We can then write (Equation 1):
or, with simplified notation:
where C is a constant.
Should the source be a graybody with emittance ε, the received radiation would conse-
quently be εWsource.
We are now ready to write the three collected radiation power terms:
1. Emission from the object = ετWobj, where ε is the emittance of the object and τ is the
transmittance of the atmosphere. The object temperature is Tobj.
#T559828; r. AK/40423/40423; en-US 84
The measurement formula
19
2. Reflected emission from ambient sources = (1 – ε)τWrefl, where (1 – ε) is the reflec-
tance of the object. The ambient sources have the temperature Trefl.
It has here been assumed that the temperature Trefl is the same for all emitting surfa-
ces within the halfsphere seen from a point on the object surface. This is of course
sometimes a simplification of the true situation. It is, however, a necessary simplifica-
tion in order to derive a workable formula, and Trefl can – at least theoretically – be giv-
en a value that represents an efficient temperature of a complex surrounding.
Note also that we have assumed that the emittance for the surroundings = 1. This is
correct in accordance with Kirchhoff’s law: All radiation impinging on the surrounding
surfaces will eventually be absorbed by the same surfaces. Thus the emittance = 1.
(Note though that the latest discussion requires the complete sphere around the ob-
ject to be considered.)
3. Emission from the atmosphere = (1 – τ)τWatm, where (1 – τ) is the emittance of the at-
mosphere. The temperature of the atmosphere is Tatm.
The total received radiation power can now be written (Equation 2):
We multiply each term by the constant C of Equation 1 and replace the CW products by
the corresponding U according to the same equation, and get (Equation 3):
Solve Equation 3 for Uobj (Equation 4):
This is the general measurement formula used in all the FLIR Systems thermographic
equipment. The voltages of the formula are:
Table 19.1 Voltages
Uobj Calculated camera output voltage for a blackbody of temperature
Tobj i.e. a voltage that can be directly converted into true requested
object temperature.
Utot Measured camera output voltage for the actual case.
Urefl Theoretical camera output voltage for a blackbody of temperature
Trefl according to the calibration.
Uatm Theoretical camera output voltage for a blackbody of temperature
Tatm according to the calibration.
The operator has to supply a number of parameter values for the calculation:
• the object emittance ε,
• the relative humidity,
• Tatm
• object distance (Dobj)
• the (effective) temperature of the object surroundings, or the reflected ambient tem-
perature Trefl, and
• the temperature of the atmosphere Tatm
This task could sometimes be a heavy burden for the operator since there are normally
no easy ways to find accurate values of emittance and atmospheric transmittance for the
actual case. The two temperatures are normally less of a problem provided the surround-
ings do not contain large and intense radiation sources.
A natural question in this connection is: How important is it to know the right values of
these parameters? It could though be of interest to get a feeling for this problem already
here by looking into some different measurement cases and compare the relative

magnitudes of the three radiation terms. This will give indications about when it is impor-
tant to use correct values of which parameters.
The figures below illustrates the relative magnitudes of the three radiation contributions
for three different object temperatures, two emittances, and two spectral ranges: SW and
LW. Remaining parameters have the following fixed values:
• τ = 0.88
• Trefl = +20°C (+68°F)
• Tatm = +20°C (+68°F)
It is obvious that measurement of low object temperatures are more critical than measur-
ing high temperatures since the ‘disturbing’ radiation sources are relatively much stron-
ger in the first case. Should also the object emittance be low, the situation would be still
more difficult.
We have finally to answer a question about the importance of being allowed to use the
calibration curve above the highest calibration point, what we call extrapolation. Imagine
that we in a certain case measure Utot = 4.5 volts. The highest calibration point for the
camera was in the order of 4.1 volts, a value unknown to the operator. Thus, even if the
object happened to be a blackbody, i.e. Uobj = Utot, we are actually performing extrapola-
tion of the calibration curve when converting 4.5 volts into temperature.
Let us now assume that the object is not black, it has an emittance of 0.75, and the trans-
mittance is 0.92. We also assume that the two second terms of Equation 4 amount to 0.5
volts together. Computation of Uobj by means of Equation 4 then results in Uobj = 4.5 /
0.75 / 0.92 – 0.5 = 6.0. This is a rather extreme extrapolation, particularly when consider-
ing that the video amplifier might limit the output to 5 volts! Note, though, that the applica-
tion of the calibration curve is a theoretical procedure where no electronic or other
limitations exist. We trust that if there had been no signal limitations in the camera, and if
it had been calibrated far beyond 5 volts, the resulting curve would have been very much
the same as our real curve extrapolated beyond 4.1 volts, provided the calibration algo-
rithm is based on radiation physics, like the FLIR Systems algorithm. Of course there
must be a limit to such extrapolations.
