Analog Galvo Driver

Analog Galvo Driver

The Scanner Optics analog galvo driver board is designed for the full series of Scanner Optics photoelectric galvanometer motors. It uses the traditional PID closed-loop control mode for stable, reliable performance, supports analog signal input, and offers a variety of configurations: different power amplifier devices drive mirrors with loads from 3 mm to 50 mm for optimal dynamic performance. This meets the speed and accuracy requirements of high-end laser scanning applications.

Key Features:

  • Based on PID control mode, stable performance, high precision, fast speed.
  • Load size 3-50mm aperture mirrors.
  • Compact size, for different application scenarios. A variety of different performance of the driver board optional.
  • Rich I/O configurations. Support ±3V to ±10V analog signal input. Support for galvanometer position, error, speed and current signal output.
  • Suitable for Scanner Optics UltraGalvo series and STGalvo series galvanometer scanners.
