For the detailed specifications please see each product link.


Glan Laser Polarizer

Glan Laser Polarizer is designed specifically for high energy laser. It is made of two same birefringence material prisms that are assembled with an air space. The polarizer with two escape windows allows ...

Wollaston Polarizer

Wollaston polarizer is made of two birefringent material prisms that are cemented together. The deviations of the ordinary and extraordinary beams are nearly symmetrical about the input beam axis,

Glan Thompson Polarizer

Thompson Polarizer Glan Thompson Polarizer is made of two α-BBO or calcite prisms cemented together. It has a wavelength from 200nm to 2300nm. α-BBO polarizer can be used from about 200nm to 1100nm, and calcite polarizer can be used from 350nm to 2300nm. This type polarizer has higher extinction ratio than air spaced polarizer. And it has the widest field angle of any design. For example, α-BBO Glan Thompson Polarizer has an angular field lager than 15 degree.

Rochon Polarizer

Rochon polarizer is one of the earliest designs, which is made of two birefringent material prisms cemented together. Both ordinary and extraordinary beams propagate collinearly down the optic axis in...

Glan Talor 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.

Depolarizer

Plane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change the plane polarization into a mix of polarization states by scrambling up the polarization,
