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 500 nm, the XRT-A achieves the precision of an air bearing 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 presice rotation is needed.
