Calcite crystal is a negative uniaxial crystal well-known for its high birefringence and transparence in broad region of spectrum. It is the ideal material for manufacturing various polarizers used in visible-IR range such as Glan-Taylor polarizers, Glan-Thompson polarizers and Glan laser polarizers. Recently, calcite plate is also widely used for time delay compensation between two orthogonally polarized ultrafast pulses.
