Small. Precise. Smart.
​​​​​​​Embedded motion systems make great products smaller.

Smallest size, high resolution, unmatched ease of use

This miniature, “all-in-one” rotary positioning stage has closed-loop position resolution better than 0.022 degrees with absolute position feedback. it provides point-to-point angular positioning with closed-loop bandwidth of ~100Hz.


The piezo-driven positioning stage has 0.5 µm resolution for precise, repeatable positioning of optics, probes, sensors and more. Absolute encoding removes the need to home the stage on power-up, eliminating errors and disruptions in processes and experiments.
The M3-LS micro stage has high stiffness and lateral stability, no backlash, and less than 10 µm runout over its full travel range.
