China Acousto-Optic Crystal Piezo-Electric Crystal Neodymium Doped Yttrium Orthvanadate

The 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 due to its wide transparency range and large birefringence. It is an excellent synthetic substituteCleaning Machine for Calcite (CaCO3) and Rutile (TiO2) crystals in fiber optical applications such as isolators, circulators, beam displacers, Glan polarizers and other polarizing optics.Specifications:
