Only 12 mm in diameter, this system is
ideal for precise, point-to-point beam
steering in a limited space, where dynamic
scanning is limited to less than 100 Hz.
The 3.3 VDC input makes it suited for
handheld and portable instruments.

Mirror positioning on your fingertip
The DK-M3-RS-U-1M-20 is a complete piezoelectric mirror
positioning 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 positioning. 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 positioner accepts direct input
of high-level digital motion commands from your system
processor, or use the USB adapter for PC control.

Low power for hand-held systems
The mirror positioning system needs only 3.3 V DC and uses
approximately 500 mW when moving or 50 mW in standby mode.
It can be powered by USB or standard batteries. The integrated
piezo motor holds position without using power.
