These fast, high accuracy, Linear Voice Coil Actuators with integrated feedback are useful tools in laser scanning.
Precision Laser Scanning can design custom motion control electronics and software for your Voice Coil Actuator requirements.


Z-Axis Focusing
X-Y laser scanners may employ a VCA to give fast Z-Axis focusing. There two common applications:

  • The X-Y scanner is a gantry system and the Z-Axis focusing is compensating for a target which has Z-Axis variation.
  • The X-Y scanner may be a galvo scan head and the Z-Axis focusing is used to produce a flat scan field without an F-Theta lens! And, can also be programmed to compensate for a target which has Z-Axis variation!

Fast Steering Mirrors (FSM)

An FSM is a single mirror which can be rapidly tilted in X and Y. The X-Y motion is accomplished with four VCAs.
