Description
Glan Laser polarizer is made of two same birefringent material
prisms that are assembled with an air space. Photonchinas 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.
