Measuring 12 mm in diameter, including closed-loop controller, DK-M3-RS-U-1M-20 Piezoelectric Mirror Positioning System rotates pre-mounted aluminum-coated mirror ±20° at up to 1,100°/sec with accuracy of 0.25° for precise, point-to-point positioning or dynamic scanning up to 100 Hz. Miniature rotary stage integrates piezoelectric motors along with position sensors, bearings, drive electronics, and firmware. Operating from 3.3 Vdc, unit accepts input via I2C, SPI, UART or analog servo interface.
