Glan Thompson polarizer is made of two calcite prisms or a -BBO prisms cemented together, which belongs to Polarization Optics. It is a kind of common Optical Element. Two types of Glan Thompsons are available, one is the standard form and the other is the long form. Their length to aperture ratios are 2.5 : 1 and 3.0 : 1 respectively. Glan Thompsons tend to have higher extinction ratio than air spaced polarizers. In the ultra violet spectrum, their transmission is limited by absorption in birefriengent materials as well as the cement layer. a -BBO polarizers and Calcite polarizers can be used from about 220 to 900nm and 350 to 2300 nm respectively.
