Compact & precise rotation stage


The XRT-U 40 is a compact and precise rotation stage driven by an ultrasonic piezo motor. With the XRT-U 40, you can achieve error motions comparable to an air bearing rotary stage, but in a smaller volume and for a lower price.

Compared to other piezo motor technologies, an ultrasonic piezo motor ensures you a non degrading and vibration proof precision without generating any vibrations during standstill. This makes the XRT-U a state-of-the-art rotation stage for applications such as micro CT scanners, metrology applications and vacuum and non-magnetic applications, such as electron microscopy.
