YVO4 Substrate
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 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.
OST Photonics offers high quality YVO4 substrates for researchers and industries. Crystal orientation, size and thickness can be customized according to your requirements.
