Beam Twisters™ are used to rotate the beams emitted by the individual diodes within a laser bar by 90°. When light is initially emitted from a laser bar, the light appears to be in the shape of a line. After passing through a Beam Twister, the 90° rotation transforms the laser bar’s light emission into a square-like appearance. A square is advantageous to a line because it allows the beam to be focused into a spot for use with fiber optics or other beam delivery systems. The Beam Twister assembly consists of a fast axis collimator and a rotation array that have been preassembled for use.
Note: Beam Twisters should be paired with a Slow Axis Collimator (sold separately) for complete collimation of the laser beam.
