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.
