Product Name: IR Silicon Monocrystal Optics, Aspherical Lenses Model NO.: D5~D150mm Coating: Ar or Reflective Coating Upon Request Customized: Customized Certification: RoHS, ISO9001 Lenses Color: Clear Material: Optical Zns, Znse, CaF2, Si, Ge, Mgf2, Fs Glass Shape: Round Transmittance: >95% Type: Aspherical Lens Usage: Optical Trademark: ICC Origin: Qinhuangdao China HS Code: 9001909090 Product Description Windows are most often used to separate two environments while allowing light to pass. Reflections from their surfaces can also be used to sample beams. Windows used in laser applications need to have low scatter, low absorption, low transmitted wavefront error, and high laser damage threshold. That's why all of our catalog windows are manufactured to laser quality, with 10 - 5 scratch dig surface quality, λ/10 TWE, and optional high power antireflection coatings on one or two surfaces. processing machine Product DescriptionChina Optical Zns, Znse, CaF2, Si, Ge, Mgf2, Fs Windows/Lens/Wafer/Prism/SliceWe could manufacture kinds of optical infrared lenses, materical can be ZnS, ZnSe, CaF2, Si, Ge, MgF2, FS etc., windows, mirror, spherical lens, cylindrical lens can be produced by infrared material.Normal specification of our infrared lenses as follow:*Material ZnSe, Si, Ge, CaF2, MgF2, FS etc.*Dimension tolerance +/-0.20mm*Thickness tolerance +/-0.20mm*Surface Quality 60-40*Flatness λ/4 at 633nm*Clear Aperture 80%*Crystals directional precision 5 min*Bevel 0.3+/-0.20mmx45 degree*Coating OptionalRange of diameterDia.0.7mm-Dia.400mmRange of curve radiusR1.5-R∞ etc.Tolerance of diameter+/-0.1, +/-0.01, +/-0.005 etc.Surface accuracyΛ , 1/2λ , 1/4λ , 1/10λ etc.Tolerance of Thickness+/-0.1, +/-0.05, +/-0.01 etc.Centration+/-2′,+/-1′ etc.Aperture N5, 1 etc.Irregularity ΔN2, 1, 0.5, 0.2 etc.Surface quality60/40, 40/20, 20/10, 10/5 etc.Basic InfoShape:RoundMaterial:Optical GlassSurface Flatness:Lambda/10@633nmSurface Quality:10-5 ~ 20/10Parallelism:<3 ArcminDiameter Tolerance:+0.00/-0.10mmThickness Tolerance:+/- 0.2mmClear Aperture:>90% of Central DiameterCoating:OptionalBevel:0.30mm X 45°Trademark:HHOPTECOrigin:JilinProduct DescriptionGerneral purpose plane windowsFlat polished surfacesLaser finish both sidesApply any anti-reflecting coatingThese general purpose plane windows are polished to lambda/10 flatness except where indicated otherwise.They are intended for for transmissive use and are parallel to better than 3 arcmin or 10 arcsec.
