Stick-slip rotation stages | XRT-A
Extremely compact & precise
The XRT-A is the only non-ultrasonic piezo stage in our portfolio, as it is driven by a stick-slip (inertia) piezo motor. Is it also our smallest rotation stage.
These miniature rotation stages are extremely compact and lightweight. The default version already achieves extrmely accurate circular motion (= radial error motion), but with the 'Active compensation' option, this rotary stage is the most accurate in the world.
Also available as non-magnetic and vacuum-compatible.
Only 1 - 2 weeks lead time for most products.

Our smallest piezo rotation stage| XRT-A
The XRT-A is driven by a stick-slip piezo motor. With our patented bearing technology in the XRT-A, one can actively compensate the radial error motion to a nanometre-level, even during rotation. This makes the XRT-A unique and the most precise piezo rotation stage on the market.
With a radial error motion smaller than 0.5 µm, the XRT-A comes close to the error motion an air bearing stage without the need of pressurized air and a large volume, and this at an advantageous price. As a result, the XRT-A is the ideal solution for vacuum and magnetic applications where a precise rotation is required.

Non-magnetic rotary stages
All of our rotary & linear stages are available as non-magnetic versions. But what does this mean exactly?
1. Xeryon stages do not generate a magnetic field, thanks to the absence of copper windings or magnets.
2. Xeryon stages can be made without any ferromagnetic materials, making them usable in magnetic fields up to 10T ('Full non-magnetic' option).
For fluctuating magnetic fields, we offer reinforced PEEK plates in order to minimize unwanted eddy current formation.
For more information on non-magnetic stages, do not hesitate to contact us.
