High Transmission Glan Laser Polarizers
UPT specially designed a high transmission Glan Laser Polarizer for online_ordering which requires high transmission. The specially designed polarizer is based on the Brewster Cut crystal, which can improve the transmission from normally >85% to 95%. This polarizer can be made from both Calcite and YVO4.
