The speed and precision of Xeryon’s products enabled us to significantly improve our microscope design and disrupt the market. Most importantly, it has allowed our customers to accelerate scientific discovery. It’s rare to achieve such a technological leap.
Director of R&D
Fluorescence microscope manufacturer
Our laser systems use a large number of motorized optics. After experiencing quality and delivery issues with our main supplier, we decided to give Xeryon a try. They have proven to be a reliable supplier, and we found their piezo stages to be much more durable than the ones we used before.
Senior Optomechanical Designer
Ultrafast laser source manufacturer
At first, I found it hard to believe this level of performance could come from such a compact package. Xeryon’s technology was the only solution that made it possible to build the machine our company had envisioned, enabling the next generation of automated test equipment. Their team was also incredibly helpful in answering all of our integration questions.

Compact & precise rotary motor | XRT-U
The XRT-U is a compact and very precise rotation stage driven by an ultrasonic piezo rotary motor. With the XRT-U, you can achieve error motion values close 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-free precision without generating any undesired dither motion during standstill. This makes the XRT-U a state-of-the-art piezo rotation stage for applications such as micro-CT scanners, metrology applications and vacuum and non-magnetic applications, such as electron microscopy.
