Birefringent Crystal Calcite

Overview:

Calcite is a negative uniaxial crystal that has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.


Although is a fairly soft crystal and is easily scratched, it is an ideal material used as visible and near IR polarizers, such as Glan Thompson, and Glan Taylor, Glan laser polarizer.
