Rotary Micro Stages

M3-RS Rotary Smart Stage with embedded controller

New Scale rotary micro stages and positioning modules feature our patented piezoelectric motors along with integrated position sensors, bearings, drive electronics and embedded firmware.

These “smart stages” have all electronics integrated into the compact rotary micro stage – no external controller required. Along with smallest system size, this makes for fastest, easiest integration into your handheld and portable systems.

Optional Components for Developer’s Kits

Each stage in the kit includes an attached flexible printed circuit (FPC) cable. You may purchase cables in other lengths, with straight or 90-degree exit angles. Beam steering kits include a mounted mirror, pre-attached to each stage. You may order additional mounted mirrors if desired. Tools to attach the mounted mirrors to the stage are included in the kit.

M3-RS-U-360 Rotary Microstage

The M3-RS-U Rotary Smart Stage Positioning Module is also available separately, without mirror or accessories. The micro stage has a continuous 360° rotation without the mirror mount limit stops used in the Beam Steering Developer’s Kits.

At only 12 mm in diameter including the embedded controller, this micro stage is ideal for scientific and industrial applications requiring precise rotational positioning in a limited space. Applications include optical tuning with gratings or filters, and sample alignment.
