    Yttrium Orthovanadate 35mm Birefringent YVO4 Laser Crystal

    YVO4

    The Yttrium Orthovanadate (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, Glan polarizers and other polarizing optics,etc


    Advantages:

    • Various size of bulk and finished high quality YVO4 crystals

    Large quantity YVO4 wedges and displacers used for fiber optical isolators and circulators, interleavers, in size of 1.25x1.25x0.5mm3 to 3x3x15mm3 to meet OEM customer's requirement;

    Quick delivery;
    Very competitive price;
