Proceedings PaperPractical Prism Polarizers
|Format||Member Price||Non-Member Price|
Various types of polarizing prisms can be made from Calcite, a natural crystal which is useful in a spectral region slightly greater than the Visible. Other crystals can be used for other ranges, but the types of prisms that can be made from them are less numerous. The basic types are reviewed, and the restrictions imposed by the optical properties of the materials are discussed. Other polarization components made from birefringent crystals, such as retarders and scramblers are also discussed.
