DescriptionCerium-doped YAG is commonly used as a phosphor in cathode ray tubes and white light-emitting diodes,Website:http://www.meta-laser.com, and as a scintillator. Yttrium aluminum garnet activated by cerium is fast with excellent mechanical properties and is chemically resistant scintillator. Mechanical properties enable to produce Ce:YAG scintillation screens down to a thickness of 30 µm. Ce:YAG detectors are excellent for electron microscopy, beta and X-ray counting, electron and X-ray imaging screens.SpecificationPolishing Specification for Optical GradeⅠOrientation Tolerence< 1°Thickness/Diameter Tolerance±0.10 mmSurface Flatness<(λ-2λ)@632nmWavefront Distortion<(2-4)λ@632nmSurface Quality80/50Parallel10ˊPerpendicular60ˊClear Aperture>90%Chammfer<0.2×45°Polishing Specification for Optical Grade ⅡOrientation Tolerence< 0.5°Thickness/Diameter Tolerance±0.10 mmSurface Flatness<(λ/2-λ/4)@632nmWavefront Distortion<(1-2)λ@632nmSurface Quality60/40Parallel1ˊPerpendicular30ˊClear Aperture>90%Chammfer<0.2×45°Polishing Specification for Optical Grade ⅢOrientation Tolerence< 0.2°Thickness/Diameter Tolerance±0.02 mmSurface Flatness(λ/4-λ/6)@632nmWavefront Distortion<(λ-λ/2)@632nmSurface Quality40/20Parallel45〞Perpendicular20ˊClear Aperture>90%Chammfer<0.2×45°Standard productsProductConcentrationAperture dimensions,mmlength,mmProduct IDPriceCe:YAG＜0.3%max.dia300.1-120　　0.3-0.6%max.dia80　　＞0.6%max.dia70　　Key ParameterTransmittance graphLuminescence spectra of Ce:YAG crystalsPulsed x ray excited and emitted decay curve
