Galvanometer-Scanner digital

Canon offers fully digital high-performance galvanometer systems based on in-house developed optical LED encoder (digital position sensor). Canon's galvanometers are available in three different motor types that support laser beam diameters from 3 mm up to 30 mm. The galvanometer scanners offer very high precision and accuracy, surpassing all analog galvanometer scanners.

Features:

  • Canon proprietary optical LED encoder (digital position sensor)
  • Digital servocontroller
  • High repeatability and linearity
  • Very high resolution
  • Extremely low thermal drift
  • Self-tuning, galvo matching software

 

Applications:

Laser eye surgery - confocal microscopy - OCT scanner - laser marking & scribing - laser projection imaging - micromachining
