High Transmission Glan Laser Polarizers

High Transmission Glan  Laser Polarizers (GHP) is a special type of Glan Laser Polarizers. The  incidence angle of the GHP is Brewster angle cut which can great improve  the transmission ray up to 98% in a wide range of wavelength without  coating. The polarizer can be made from Calcite and YVO4 crystals. In  order to get high transmission of wide range of wavelength, the  polarizers are not recommended to use for large acceptance angle.  Typically used is within +/-5.

Features:
