AT 21

Tip or Tilt scanning mirror

Tip or Tilt scanning mirror АТ21 is intended to control laser beam direction over alone plane and can be used for scanning and steering.

Mirror AT21 can be used:

  • in laser technology machines for engraving, annealing, marking, cutting, welding etc...,
  • in laser beam communication systems for to stabilize laser beam over large distances,
  • in adaptive optics systems for tip and tilt distortions compensation,
  • in scanning and display devices.
