Best select-grade calcite
Our Glan-Laser Calcite Polarizers are designed for demanding applications requiring extreme polarization purity and high resistance to laser damage. Glan-laser polarizers are air-spaced, select-grade calcite prism pairs with the prism interface angles optimized for minimum insertion loss. Two escape ports provide an exit for the rejected polarization component, avoiding dangerous absorption of laser power by the polarizer housing. This allows these polarizers to be used in Q-switched laser cavities and other multiple pass applications.
To maximize transmission, these polarizers are offered with a choice of three broadband antireflection coatings or a special V-coating for 1064 nm. The housing has been designed to mount into our standard 25.4 mm optic holders, rotary stages, and precision positioning components. The output polarization axis is clearly marked on the housing.
