32-969 9mm Dia. x 18mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 32-969 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 18mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is made from the high-grade material, n-BK7 Schott, which is known for its excellent optical properties. The base shape of the lens is circular, and it features a standard spherical geometry. The thickness at the edge of the lens is 1.47mm, while the center thickness measures 2.6mm. The effective focal length (EFL) is 18mm, and the radii of curvature for the first and second surfaces are 18.15mm and -18.15mm, respectively. The back focal length (BFL) is 17.12mm.
The lens is coated with MgF2 on both the front and back surfaces, which is a standard coating that provides excellent transmission in the 400-700nm wavelength range. This coating enhances the lens's performance by reducing reflection and increasing transmittance.
