High Birefringence Laser Crystals 0.5deg Negative Uniaxial Crystal

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. General Specifications Of Calcite: Dimension Tolerance 0.1mm Optical Axis Orientation 0.5deg Surface Quality 20/10
