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.CRYSMIT Glan-Taylor Polarizers produce extremely pure linear polarization with an extinction ratio greater than 100,000:1 and are meant for use with laser beams in the 350-2300nm wavelength range. The polarizer with no side escape windows is suitable for low to medium power application where the side rejected beams are not required .

What is a Glan Taylor polarizer ?

A Glan-Taylor prism is a prism made from a birefringent crystal(Such as Alpha-BBO, Calcite and YVO4) and used as a polarizer or polarizing beam splitter. It is one of the most common types of modern polarizing prism. It was first described by Archard and Taylor in 1948.

How does a Glan Taylor polarizer work ?

In our Glan Taylor polarizers, this birefringence causes the ordinary polarization component of an incident beam to undergo total internal reflection at an internal glass-to-air interface. The light transmitted through the polarizer then consists of only the remaining extraordinary polarization component.
