The New Scale Technologies DK-M3-RS-U2-2M-20-L is a complete piezoelectric beam steering system with a familiar galvo form factor, but a drastically smaller size: only 11.75 mm long x 21.9 mm wide x 16 mm tall including the embedded closed-loop controller. The mounted aluminium-coated mirror moves at up to 1,100 deg per second with repeatability of +/-0.05 deg for precise, point-to-point beam steering.

Patented piezoelectric motors along with position sensors, bearings, drive electronics and embedded firmware are all integrated inside each of the two miniature rotary stages. We’ve eliminated the extra bulk of a separate external controller. Along with smallest system size, this makes for fast, easy integration into your system. The beam steering system accepts direct input of high-level digital commands from your system processor or use the USB adapter to power and control the system from a PC. Input is only 3.3 VDC. Embedded controller means tiny size plus fast, easy integration
