Glan Laser Prism / GLPB_GLP
The Glan Laser polarizer are designed to provide an enhanced laser damage threshold for high power lasers and high energy laser pulses. The transmission loss is minimal, and a high extinction ratio below 5×10−5 is obtained. The Calcite type that can be used in the visible to the infrared region, and α-BBO crystal type usable in the ultraviolet region are available.
