High transmission

High transmission polarizer

High Transmission Glan Laser Polarizer is a special type of Glan Laser Polarizers. Its incidence angle is brewster angle cut which can greatly improve the transmission ray up to 98% in a wide range of wavelength without coating. The polarizer can be made from Calcite or YVO4 crystals. In order to get transmission of a wide range of wavelength, the polarizers are not recommended to use for large acceptance angle. It is typically used at the angle within+/-5°.
