Details

UV fused silica double convex lenses are made of UV fused silica.
UV fused silica glass has a wider spectral range (185nm-2.1 μ m) than K9 optical glass. It has excellent transmittance in the UV band, lower refractive index, better uniformity, smaller thermal expansion coefficient, and higher chemical resistance and low fluorescence. It can be used to make various optical elements. A biconvex lens focuses light into a point with a positive focal length, consisting of two convex surfaces with equal radii. If the conjugate ratio (object distance: image distance) is between 5:1 and 1:5, a biconvex lens is the best choice for reducing aberrations. Outside this range, a plano convex lens is usually preferred.
The intelligent UV fused silica biconvex lens provides lenses of various sizes and focal lengths, coated and uncoated products, and broadband antireflection coatings that can be used in UV (UV 250-400nm) wavebands to meet your various applications in different scenes and wavebands. Guangtan Intelligent can also customize lenses of other specifications according to your actual needs.
