Yttrium Vanadate (YVO4) crystal is a positive uniaxial crystal grown using the Czochralski method. It has good mechanical and physical properties and is ideal for optical polarizing components because of their wide transparency range and large birefringence. It’s an excellent synthetic substitute for Calcite (CaCO3) and rutile (TiO2) in many applications including fiber optic isolators and circulators, beam displacers, Glan polarizers and other polarizing optics.
