Size tol.: ±0.05 x±0.05 x±0.1mm Yttrium orthovanadate (YVO4) is a good birefringent single crystal with excellent physical and optical properties. Due to its wide transparency range, high transmittance, large birefringence and easily processed character, the material can be widely used in optical components such as fiber optical isolators and circulators, beam displacers and other polarizing optics, etc.Applications:Fiber optical isolators and circulators, beam displacers and other polarizing optics, etcThe yttrium orthovanadate (YVO4) is a positive uniaxial crystal grown with Czochralski method. It has good mechanical and physical properties and 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, beam displacers, Glan polarizers and other polarizing optics, etc.Comparation with other Birefringent crystalsCompared to Calcite, YVO4 has better temperature stability and physical and mechnical properties. Calcite is hard to obtain high optical quality because of its low susceptibility to moisture and low hardness.Compared to Rutile (TiO2) which exhibits too high hardness, YVO4 is easier to be handled for optical surface processing that greatly reduces cost of fabrication, especially for batch production. Compared to LiNbO3, although they have similar mechanical and physical properties, YVO4 has more than three times larger birefringence, that makes your design more compact. |
