Two-Axis Two-Mirror
Beam Steering System

Miniature piezo smart stages
with built-in controllers enable simple,
precise point-to-point beam steering▪ Piezo stages with continuous 360° rotary motion▪ Mounted mirrors, laser and two-axis base
▪ Each rotary stage only 11.75 x 21.9 x 16 mm▪ Closed-loop controller embedded in each stage- No separate electronics needed- 3.3 VDC input- Direct digital input of motion commands( I2C, SPI, or UART)▪ Angular resolution ~21.9727 mdeg closed loop
- Built-in absolute position sensor▪ Millisecond step and settle times
0.5 deg in 16 ms closed loop
0.5 deg in 1.2 ms open loop
▪ Holds position with zero power and no jitterTwo-axis beam steering on your fingertip
The DK-M3-RS-U2-2M-20-L is a complete piezoelectric beamsteering system with a familiar galvo form factor, but a drasticallysmaller size: only 11.75 mm long x 21.9 mm wide x 16 mm tall
including the embedded closed-loop controller.
The mounted aluminum-coated mirror moves at up to 1,100 deg
per second with repeatability of +/-0.05 deg for precise, point-topoint beam steering.

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 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 systemprocessor or use the USB adapter to power and control thesystem from a PC. Input is only 3.3 VDC.

APPLICATIONSThis system is ideal for precise, pointto-point beam steering in a limited
space, with dynamic positioning up to100 Hz. The 3.3 VDC input makes itsuited for handheld/portable
instruments.
