Frequently Asked Questions

The specifications of the Glan Taylor polarizer include material options of a-BBO, Calcite, or YVO4, a wavelength range of a-BBO: 200-3500nm, Calcite: 350-2300nm, YVO4: 400-5000nm, extinction ratio of Calcite: <5x10-5; a-BBO: <5x10-6; YVO4: <5x10-6), parallelism of <1arcMin, surface quality of 20/10, beam deviation of <3arcminutes, wavefront distortion of l/4@633nm, damage threshold of >200MW/cm2, coating of single-layer MgF2, and mount of black anodized aluminum.

The different part numbers and specifications of the Glan Taylor polarizer for different materials include a-BBO Glan Taylor Polarizer (PGT1206, PGT1208, PGT1210, PGT1212, PGT1215, PGT1306, PGT1308, PGT1310, PGT1312, PGT1315, PGT1320, PGT1706, PGT1708, PGT1710, PGT1712, PGT1715, PGT1720), Calcite Glan Taylor Polarizer (PGT2006, PGT2008, PGT2010, PGT2012, PGT2015, PGT2020), and YVO4 Glan Taylor Polarizer (PGT3006, PGT3008, PGT3010, PGT3012, PGT3015, PGT3020).

The polarizer with no side escape windows is suitable for low to medium power where the side rejected beams are not required, which is suitable for a wide variety of situations particularly with collimated input beams.

The Glan Taylor polarizer features air-spaced close to Brewster's Angle Cutting, high polarization purity, short length, and suitability for low to medium power applications where the rejected beam is not required.

A 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, making it a relatively thin polarizer.
