Glan Taylor Polarizer
Glan Taylor prism polarizer is made of two same birefringent material prisms that are assembled with an air space. It has a length to aperture ratio less than 1.0 makes it a relatively thin polarizer. The polarizer with no side escape windows are suitable for low to medium power where the side rejected beams are not required. The angular field of different materials of polarizers listed below for comparison.
