Product Description
YVO4
YVO4 Yttrium Vanadate, undoped YVO4 crystal is an excellent birefringent optical crystal, with good light transmittance in the wide range of visible and near infrared, large refractive index value and birefractor index difference. Compared to other important birefringent crystals, the YVO4 Crystal has higher hardness than Ice Continent Stone (CaCO3Single crystal), good machining performance, insoluble in water, and can be artificially grown (it needs to rely on natural resources); YVO4 crystal is easier to grow a large pieces of high quality crystal, than Rutile single crystals (TiO2), the price is much lower than Rutile. These excellent features make the YVO4 Crystal rapidly become a new type of birefringent optical material, widely used in the photoelectric industry. In optical fiber communication equipment, it requires a lot of pure YVO4 crystal made of various spectral and polarization components, such as optical isolator, circulator, optical splitter, and grand series polarizer, etc. YVO4 crystal and Rutile crystal combination, also can get the ideal temperature compensation effect, greatly improve the temperature stability of optical communication system.
