Two-axis beam steering on your fingertip
The 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 aluminum-coated mirror moves at up to 1,100 deg per second with repeatability of +/-0.05 deg for precise, point-to-point 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 system processor or use the USB adapter to power and control the system from a PC. Input is only 3.3 VDC.
The Developer’s Kit
The DK-M3-RS-U2-2M-20-L Beam Steering System Developer’s Kit includes two smart stages, mounted mirrors, a 650nm collimated laser, base, demo board, cables, USB adapter and software for system evaluation and development.
Smart Stages with mounted mirrors, laser and base
The standard aluminum-coated mirrors are pre-mounted on the M3-RS-U2 rotary smart stages. The stage’s builtin controllers accept direct digital control via the FPC connector.
