DescriptionCalcium carbonate crystal (formula for CaCO3) is a kind of uniaxial crystal,Website:http://www.meta-laser.com, which is the most pure crystal in the carbonate rocks. Its birefringence is large, range of spread spectrum is wide, and show a certain size of the diamond shape,it has the largest polarized light and polarized light performance,it is suitable for the visible and near infrared polarization material and the grand ideal material used in the glen Taylor, glen Thompson and glen laser polarizing film.SpecificationParameters of materialsMaterialsCaCO3transmission region350nm-2300nmOrientation<001>±0.5ºCoatingsR<0.5%Polishing Specificationfor Laser GradeOrientation Tolerence< 0.5°Thickness/Diameter Tolerance±0.1 mmSurface Flatness<λ/8@632nmWavefront Distortion<λ/4@632nmSurface Quality10/5Parallel30〞Perpendicular15ˊClear Aperture>90%Chammfer<0.2×45°Standard productsMaterialAperture dimensions,mmlength,mmCoatingsProduct IDPriceCaCO350x5030R<0.5% 10x100.5R<0.5% 5x50.5R<0.5% 1'x1'1R<0.5%
