Product Description General Introduction:Raytek UV fused quartz biconcave cylindrical lens can choose not to be coated, but also to be coated with a variety of multilayer antireflective coatings. All lenses are guaranteed λ/ 8 surface accuracy and 20-10 scratch-dig surface quality. UV fused silica is a highly pure synthetic amorphous silica, which can provide transmittance of 195-2100 nm. This amorphous colorless quartz glass combines very low thermal expansion coefficient, good optical quality and excellent transmittance in the ultraviolet band. Moreover, it does not emit fluorescence under ultraviolet light and is radiation resistant..Products Name: Silica Bi-Concave LensesAlias: UV FUSED SILICA Bi-concave Lenses,UV FUSED SILICA Bi-concave Lenses, Optical Concave lens, UV FUSED SILICA optical concave lens, Visible UV FUSED SILICA Bi-concave Lens, Visible Bi-concave lens, IR Bi-concave lens, NIR Bi-concave lens, 1064nm Bi-concave lens, Uncoated Bi-concave lens,Double concave lens,etcLens Options:Optional I:UV FUSED SILICAfrom CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,ETCOptional II:Equivalent UV FUSED SILICAMade in China, C-laser own brands Main Optical Tech Specification:Tech DataDescriptionLens ShapeBi-Concave (Double Concave)MaterialUV FUSED SILICASurface Quality20-10 scratch-digSurface Flatnessλ/8Surface Accuracy, Irregularityλ/8Surface Accuracy, Power1.5 λCentration≤3 arc minChamfers0-0.8 mm face widthChamfers Angle Tolerance45° ±15°, typicalFocal Length Tolerance±1 %Clear Aperture≥central 90% of diameterEffective Focal Length(EFL)From -50mm to -1000mmMain Cooperation Materials Manufacturers:CORNING, OHARA, SCHOTT, LEONI, AGC,HELLMA, NIKON,VITRON,C-LASER,ETCMain Export Countries & Areas:Usa, Uk, Japan, Germany, Spain, France, Swiss, Korea, Russia, Pakistan, India, Portugal, Canada, New Zealand, Australia, Saudi Arab, Turkey, Finland, Poland ,etc.Raytekoptics Extra value added services offered:1).
