32-979 50mm Dia. x 50mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 32-979 is a high-quality double-convex lens, boasting a 50mm diameter and a 50mm focal length. 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 esteemed N-BK7 Schott material, a borosilicate glass known for its excellent optical properties. The lens features a standard MgF2 coating on both the front and back surfaces, which enhances its performance across the 400-700nm wavelength spectrum.
The geometry of the lens is meticulously designed, with an edge thickness of 7.39mm and a center thickness of 16mm. The lens's effective focal length (EFL) is 50mm, and its back focal length (BFL) is 45.3mm. The first and second radii of curvature (R1 and R2) are 74.78mm and -74.78mm, respectively.
This lens is a spherical type, with a base shape of a circle. It is a convex-convex lens, meaning both its surfaces are curved outwards. The lens's diameter is 50mm, and it does not have any specified inner or outer radii.
