Photonchina’s Glan-Thompson Polarizer is made of two cemented calcite (or a-BBO) prisms that are at the highest optical level. When the unpolarized light enters Glan-Thmopson Polarizer, it will separate at the intersection of the two calcite crystals. S-polarized light (e-ray) then goes on and P-polarized light (o-ray) will be reflected.
Function of Glan Thompson Polarizer
Thanks to the large field of view, the polarizer is ideal for highly converging or diverging beams. They provide high polarization and great transmission in the two emerging beams which are useful if it is required to utilize both linear polarization states.

HIGH TRANSMSSION POLARIZER
High Transmission Glan Laser Polarizers is a special type of Glan Laser Polarizers. Its incidence angle is brewster angle cut which can greatly improve the transmission ray up to 98% in a wide range of wavelength without coating. The polarizer can be made from Calcite or YVO4 crystals. In order to get transmission of a wide range of wavelength, the polarizers are not recommended to use for large acceptance angle. It is typically used at the angle within+/-5®.
