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