Brewster Angle Polarizer

High Transmission Glan Laser PolarizerHigh Transmission Glan Laser Polarizer(Brewster Angle Polarizer) is designed such that all four interfaces for the transmitted extraordinary beam are at Brewster’s angle. This results in a transmission to p-polarized input beams as high as 98%. Note that a lateral displacement is introduced to the emerging beam. Two escape windows are included. For the high transmission of wide range of wavelength, the polarizer’s acceptance angle should be within ±5°.
