Glan Laser polarizer is made of two same birefringent material prisms that are assembled with an air space. tonchina's polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratch dig surface quality specifications are assigned to these faces.

tonchina’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 larization states. Â
