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:
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.
