Here's a concise summary and technical interpretation:FeatureTechnical Benefit>99.7% transmittance @ 1064 nmMinimal energy loss, ideal for high-power laser systems.Anti-reflective (AR) coatingReduces Fresnel reflections (typically <0.2% per surface), prevents ghost beams, and protects the laser source from back-reflection damage.Ultra-low wavefront distortionMaintains beam quality (M2), critical for precision applications like lidar, laser marking, or microscopy.SpecificationMaterial:Fused Silica, SapphireDimensions:from 2mm to 500mm, customized according to requirementsThickness1 to 50mm (subject to dimensions)Dimension/Thickness Tolerance:up to 0.02mmParallelism:up to 3arcsecFlatness:up to 1/10L PV@633nmSurface Quality:up to 10-5Clear Aperture:>90% centeredCoatings:AR coating from UV-IRLIDT:>33J/cm2@1064nm, 5.4ns, 10HzRelated ProductsInspectionsCompany HistoryProduction LineFAQQ: What are your main products?A: Optical Components: Aspherical Lenses, Spherical Lenses, Cylindrial Lenses, Lens Assemblies, Optical Windows, Optical Mirrors, Optical Prisms, Optical Filters, and Other Special Shaped Optics......
