High Precision Calcite Birefringent Crystals
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers such as Glan Taylor, Glan Thompson and Glan laser. It has high birefringence, wide spectral transmission and availability in reasonably sized rhombs.
