Product Name: Laser Crystal Yvo4 Shipping: FedEx, UPS, DHL... Trademark: FineWin Transport Package: Box Specification: customerised Origin: China Product Description 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 substitute for Calcite (CaCO3) and Rutile (TiO2) crystals in fiber optical applications such as isolators, circulators, beam displacers, Glan polarizers and other polarizing optics.Specifications:Dimension tolerance(W ± 0.1 mm) x (H ± 0.1 mm) xL( 0.05mm)Wavefront distortion:l/8 @ 633 nmClear aperture:> 90% central areaFlatness:l/8 @ 633 nmScratch/Dig code:10/5 to MIL-O-13830AParallelism:better than 10 arc secondsPerpendicularity:5 arc minutesAngle tolerance:Dq < ±0.5°, Df < ± 0.5°AR coating:R< 0.2% at 1550nmWedge Angle tolerance:0.1°(wedges)Applications:Fiber Optic Isolator (YVO4Wedges)Beam Displacers,CirculatorsInterleaver
