Glan Laser polarizer is made of two same birefringent material prisms that are assembled with an air space. Photonchina’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.
Photonchina Feature：
●Air-spaced
●Close to Brewster's Angle Cutting
●High Polarization Purity
●Short Length
●Wide Wavelength Range
●Suitable for medium power application
Glan Taylor polarizer is made of two birefringent prisms that are assembled with an air space.
The polarizer with no side escape windows is suitable for low to medium power application where the side rejected beams are not required.
