Calcite is a negative uniaxial crystal that has high birefringence, wide spectral transmission, and availability in reasonable-sized rhombs. It’s good material used as visible and near IR polarizers. MTI carefully inspects the raw calcite crystals which are grown by nature and provides Calcite components with the highest quality and lowest price.
