Glan Thompson Prisms

Available with either 15 degree or 25 degree full angular fields
Cemented surfaces handle up to 5W/cm2 pulsed
E-ray transmittance better than 90%
Provided in a convenient metal mounting cell

These polarizing prisms are the simplest form of calcite polarizer. They are cemented, making them only useful for relatively low power applications. They have a wide and symmetrical field of view and make extremely versatile general purpose polarizers. The o-ray is absorbed in the material surrounding the prism and the e-ray is transmitted. Two versions are offered having different length/aperture ratios and consequently different angular fields. These prisms are normally provided in a metal cell but since they are cemented together they can be supplied unmounted if required.
