High Transmission Glan Laser Polarizer |
 |
 |
Brewster angle cut for highest transmission without AR-coating. | High Transmission Glan Laser Polarizers is a special type of Glan Laser Polarizers. The incidence angle is Brewster cut which can greatly improve the transmission up to 98% in a wide range of wavelengths without coating. The polarizer can be made from Calcite and YVO4 crystals. In order to get high transmission over a wide range of wavelengths, the polarizers are not recommended to use for large acceptance angles, typically used within ±5°. |  |
