Product Details
Description
Yttrium Vanadate (YVO4) crystals have good mechanical and physical properties and are ideal for optical polarizing components because of their wide transparency range and large birefringence. Yttrium Vanadate(YVO4) is a positive uniaxial crystal grown with Czochralski method. It has good temperature stability and physical and mechanical properties.
It is ideal for optical polarizing components because of its wide transparency range and large birefringence. It is an excellent synthetic substitute for Calcite (CaCO3) and Rutile (TiO2) crystals in many applications including fiber optic isolators and circulators, interleavers, beam displacers and other polarizing optics.
