CaF2 optical crystalsCalcium Fluoride (CaF2 or Fluorite) crystals are transparent in wide spectrum band. The product finds use in windows,Website:http://www.meta-laser.com, lenses operating in UV and IR spectrum band. Laser Use: Calcium Fluoride is also used as a host lattice for laser crystals. Due to its composition, CaF2 has a much longer useful life than most materials when used in fluorine environment.Features:Highest broadband transmittance from deep UV to IR (130 nm up to 8 microns)Low refractive index (nd= 1.43384)Low dispersion (vd= 95.23)Maximum laser durability in Excimer Laser optics (157nm, 193nm, 248 nm)Applications:IR opticsOptics for astronomical instrumentationMicroscope opticsSpectroscopy opticsUV opticsLaser windowsExcimer Laser OpticsMicrolithography OpticsSpecificationCalcium fluoride crystal provides great transmission from the UV to the IR (0.13-11?m). Sythetic CaF2 is used to improve deep UV transmission and to increase the damage threshold. Calcium Fluoride (CaF2) is available doped with Europium as a gamma-ray scintillator.Physical PropertiesCrystal typecubicLattice constant, ?a=5.462Density, g/cm33.18Melting point,?1360Refractive index @ 1.0?mn=1.4289Transmission range, ?m0.13-10Specifications for CaF2 windowsSpectal rangeUV, VIS, IRSurface quality40-20 S & DClear aperture90% of the diameterdiameter tolerance+0, -0.1 mmThickness tolerance?0.1parallelism<3 arcminSurface flatness?/4 @ 633 nmPolishing Specification for Optical Grade?Orientation Tolerence< 1?Thickness/Diameter Tolerance?0.10 mmSurface Flatness<(?-2?)@632nmWavefront Distortion<(2-4)?@632nmSurface Quality80/50Parallel10?Perpendicular60?Clear Aperture>90%Chammfer<0.2?45?Polishing Specification for Optical Grade ?Orientation Tolerence< 0.5?Thickness/Diameter Tolerance?0.10 mmSurface Flatness<(?/2-?/4)@632nmWavefront Distortion<(1-2)?@632nmSurface Quality60/40Parallel1?Perpendicular30?Clear Aperture>90%Chammfer<0.2?45?Polishing Specification for Optical Grade ?Orientation Tolerence< 0.2?Thickness/Diameter Tolerance?0.02 mmSurface Flatness(?/4-?/6)@632nmWavefront Distortion<(?-?/2)@632nmSurface Quality40/20Parallel45?Standard productsMaterialProductsAperture diamensions, mmThickness,mmSubstratecoatingsProduct IDPriceCaF2windowsdia81?Uncoated??dia100.5?dia101?dia25.41.5?dia25.42?dia25.43?dia38.15?dia50.86?10x102?10x60.5?
