Fused Silica Biconvex Lens

The fused silica biconvex lens has two convex surfaces and a central axis, which is used in the optical system to change the beam focusing characteristics. The fused silica material has the characteristics of high purity and high temperature melting, which makes the biconvex lens have excellent light transmittance and thermal stability. It has a wide spectral range (185nm-2.1 μ m), excellent transmittance in the ultraviolet band, lower refractive index, better uniformity, smaller coefficient of thermal expansion, high chemical resistance, and low fluorescence. It can be coated with MgF2, UV-AR, UV-VIS, VIS-EXT, VIS-NIR, NIR I, NIR II, Telecom NIR, SWIR, SWIR, YAG-BBAR and other film systems.
