UPR-120
Ultraprecision Rotation Stage
Excellent Stability and Travel Accuracy

 Unlimited travel range
 Velocity to 360 °/s
 Incremental angle measuring system with
0.00002° resolution
 Clear aperture with 35 mm diameter
 Optional: Air bearings for optimized
flatness

Reference-class rotation stage
High travel accuracy. High position resolution due to incremental encoder with analog signal transmission
(sin/cos, 1 Vpp)
Magnetic direct drive
Ironless magnetic direct drive (torque motor) for high velocity and acceleration. High position resolution.
Fields of application
Industry and research. Metrology, semiconductor manufacturing and testing, synchrotron applications
