Glan Taylor Polarizer.docx
Glan Taylor 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.
Air-spaced
Close to Brewster's Angle Cutting
High Polarization Purity
Short Length
Wide Wavelength Range
Suitable for medium power application
