  • Product Detail

    Glan-Thompson polarizers consist of two cemented prisms made from the highest optical grade of calcite or a-BBO crystal. Unpolarized light enters the polarizer and is split at the interface between the two crystals. The ordinary rays are reflected at each interface, causing them to be scattered and partially absorbed by the polarizer housing. The extraordinary rays pass straight through the polarizer, providing a polarized output.
