Glan Taylor Polarizer

Optics >>> Polarizer >>> 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 application where the side rejected beams are not required, which is suitable for a wide variety of applications, particularly with collimated input beams. The angular field of different materials of polarizers listed below for comparison.

Angular Field versus 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.
