Galvo Scanner Controller

  • This GL4 scanner controller is optimised for Aerotech’s family of AGV scanners to provide industry leading settling times, long-term thermal stability, and micron-level tracking accuracy due to advanced features such as full state feed-forward, 192 kHz servo rates, and look-ahead-based velocity control. 
  • The GL4 uses advanced interpolation electronics to provide up to 26-bits of effective resolution while onboard real-time 2D calibration ensures accurate beam placement over the entire field of view.
  • The ability to accurately place a laser spot as a function of X/Y axis position is a key feature of Aerotech’s linear positioning tables for laser processing applications. With the release of the GL4, this functionality is now available for scanner applications. 
  • The ability to accurately trigger the laser as a function of position removes the need to program mark, jump, and polygon delays, resulting in reduced programming complexity. 
  • These power devices inject thermal energy into the scanner head causing drift in the feedback positions and changing offsets between the mirrors, which reduce marking accuracy.
