A Glan Laser Prism Polarizer is made of two same birefringent material prisms assembled with an air space in between. The polarizer is designed to have less reflection loss at the two constituent prisms’ interface. The polarizer with two escape windows allows the rejected beam to escape out of the polarizer, which makes it more desirable for high-power lasers.

CRYSMIT offer Glan Laser Polarizer made from Calcite, Alpha-BBO, or YVO4, featuring high extinction purities, minimum insertion loss, reliable damage threshold and escape window for high power lasers application.Various broadband AR-Coatings from UV to MWIR are available as standard versions, whilst other coatings and specifications could be tailored upon request.
