Glan Taylor Polarizers

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


            a -BBO, 200-300nm


            a -BBO, 300-700nm


            a -BBO, 700-3000nm


            Calcite, 350-2300nm


            YVO4, 500-4000nm


Features:

Air-spaced
Close to Brewster's Angle Cutting. 
High Polarization Purity. 
Short Length. 
Suitable for low to medium power application where the rejected beam is not required.
