Newport 10GL08AR.18

The 10GL08AR.18 Glan-Laser Calcite Polarizer is designed for demanding applications requiring extreme polarization purity and high resistance to laser damage. 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.18 broadband IR antireflection coating with a 1000 to 1550 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.
