63-834 12mm Dia. x 75mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
This is a 12mm diameter, 75mm focal length double-convex lens, specifically designed for the visible to near-infrared (VIS-NIR) spectrum, covering the wavelength range of 400-1000nm. The lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock.
The lens is made of fused silica, a material with a high transmittance across a wide range of wavelengths, making it ideal for applications in the VIS-NIR spectrum. The lens features a front and back coating of edm visnir0sp2002000, a coating specifically designed for VIS-NIR applications, further enhancing its performance in this spectrum.
The lens has a base shape of a circle and a geometry that includes an edge thickness of 2.06mm and a center thickness of 2.59mm. The effective focal length (EFL) is 75mm, and the radii of curvature are 68.36mm for the first surface and -68.36mm for the second surface. The back focal length (BFL) is 74.11mm.
This lens is a spherical lens, meaning it has a spherical surface, and it is a convex-convex lens, indicating that both of its surfaces are curved outwards. This design provides a strong converging power, making it suitable for various applications that require image formation or light concentration.
