63-591 30mm Dia. x 120mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 63-591 is a high-quality double-convex lens, boasting a 30mm diameter and a focal length of 120mm. 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 crafted from the esteemed N-BK7 Schott material, a borosilicate crown glass known for its excellent optical properties. The base shape of the lens is circular, and it features a standard spherical geometry. The first radius of curvature (R1) is 123.17, while the second radius of curvature (R2) is -123.17, indicating the double-convex nature of the lens.
The lens has a thickness of 3.17mm at the edge and 5mm at the center. The effective focal length (EFL) is 120mm, and the back focal length (BFL) is 118.34mm. The lens is coated with MgF2 on both the front and back surfaces, which is a standard coating known for its broadband anti-reflection properties in the 400-700nm wavelength range.
