Glan Taylor Polarizers

Specifications Air-spaced

Close to Brewster's Angle Cutting.

High Polarization Purity.

Short Length.

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