Glan Thompson Polarizers
The Glan Thompson polarizer is made of two calcite prisms or a-BBO prisms cemented together. 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. Calcite and a-BBO polarizers polarizers can be used from about 350 to 2300 nm and 220 to 900nm respectively.
