38mm Laser Beam Directing & Positioning

Beam Switching Unit

The Beam Switching Unit contains a laser beam bending mirror mounted on precision linear bearings and can be translated in and out of the beam path. The kinematic laser beam bender provides a 90º beam displacement with a 38mm clear aperture. Kinematic correction with 80 pitch adjustment screws provides precise, repeatable alignment. The BSU-38 provides a method to "Time-Share" or redirect the laser beam.
