Product DescriptionProduct DescriptionCylindrical lenses are specialized optical elements that focus or diverge light along a single axis, unlike spherical lenses that act symmetrically. Here's a structured overview:SpecificationMaterials:Optical Grade Glass, N-BK7, UV fused silica, CaF2, ZnSe, ZnS, Ge, Si, Sapphire, etc.Diameter:1.5mm-550mmDiameter Tolerance:±0.05 mm (precision ±0.01mm)Thickness:0.5mm-100mmThickness Tolerance:±0.05mm (precision ±0.01mm)Focal Length Tolerance:±1 %Surface Quality:20-10 scratch-dig (up to 10-5 available)Flatness:PV<1/4L@ 633nm (up to 1/10L); RMS<1/40LSurface Roughness:Rq<0.5nmCentration:<3 arcmin (1 arcmin precision)Center:ETV<0.008mmChamfer:<0.1mmClear Aperture:≥90 % of DiameterAOI:0-55degCoatings:single-layer MgF2, broadband VIS, VIS-NIR, NIR I/II, telecom, or high-energy laser V-coatings (266nm, 355nm, 532nm, 1064nm, etc.)Key Features1. Single-Axis Curvature: Optical power is applied in one dimension (e.g., X or Y axis), while the perpendicular axis remains planar. 2. Asymmetric Light Shaping: Convert collimated light into a line or sheet, or transform elliptical beams (e.g., laser diodes) into circular profiles. 3. Types:Plano-Convex/Concave: One curved surface, one flat.Biconvex/Concave: Curved surfaces with radii in the same axis.Achromatic: Paired elements to reduce chromatic aberration.ApplicationsAstigmatism Correction: In ophthalmology, toric lenses (a form of cylindrical lens) correct corneal astigmatism. Laser Beam Circularization: Reshape elliptical diode laser outputs into symmetric beams. Line Illumination: Generate uniform light sheets for barcode scanning, machine vision, or medical imaging (e.g., OCT). Spectroscopy: Focus light onto slit apertures or linear detector arrays.InspectionsProduction LineCompany HistoryFAQQ: 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......
