The 10GL08AR.16 Glan-Laser Calcite Polarizer is 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 this polarizer to be used in Q-switched laser cavities and other multiple pass applications. This polarizer has Newport's AR.16 broadband NIR antireflection coating with a 650 to 1000 nm wavelength range. The housing has been designed to mount into our standard 1 inch (25.4 mm) optic holders, rotary stages, and precision positioning components. The output polarization axis is clearly marked on the housing.
