Two-axis beam steering on your fingertip
The DK-M3-RS-U-2M-20-L is a complete piezoelectric beam
steering system with a familiar galvo-scanner form factor, but a
drastically smaller size: only 12 mm diameter including the
embedded closed-loop controller.
The mounted aluminum-coated mirror moves at up to 1100
degrees per second with accuracy of 0.25 degrees for precise,
point-to-point beam steering. The mirror range is +/- 20 degrees.

Embedded controller means tiny size plus
fast, easy integration
Patented piezoelectric motors along with position sensors,
bearings, drive electronics and embedded firmware are all
integrated into the miniature rotary stage.
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 or analog motion 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.
