Optics Edge with Black Paint Optical Plano Concave Asperical Lens

Optics Edge with Black Paint Optical Plano Concave Asperical Lens Aspherical LensesAspheric Lenses are used to eliminate spherical aberration in a range of applications, including bar code scanners, laser diode collimation, or OEM or R&D integration. Aspheric lenses utilize a single element design which helps minimize the number of lenses found in multi-lens optical assemblies. Products are widely used in optical equipment, teaching, industrial lenses, camera, video shooting, automation, medical, measuring and surveying equipment, aviation, astronomy, etc.. So it requires different materials for different work range.our products cover ultraviolet, visible light and infrared band. Product NameOptics Edge with Black Paint Optical Plano Concave Asperical Lens EdgeBlack Paint SizeDia 10mm to Dia 250mmManufacturing accuracy of aspherical lenses or according to customer's need ItemCapabilityTolerancesSilverGoldPlatinumOuter Diameter10mm-250mm>=±0.10mm±0.05mm±0.01mmCenter Thickness>=1mm>=±0.10mm±0.05mm±0.02mmWedge(TIR)>0.002mm0.100mm0.050mm0.010mmAsphericity (@50mm dia)up to 5mm2mmSurface Figure PV@633nmLambda/2>1.5LambdaLambda0.2um0.2um0.06umRoughness0.5nm RMS>2nm RMS2nm RMS
