This is a 12mm diameter, 48mm focal length double-convex lens, coated with MgF2 for enhanced performance. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry.
The lens is designed with a base shape of a circle and features a spherical geometry. The edge thickness is 2mm, while the center thickness is 2.74mm. The effective focal length (EFL) is 48mm, and the back focal length (BFL) is 47.09mm. The first radius of curvature (R1) is 49.14mm, and the second radius of curvature (R2) is -49.14mm.
The lens is made of n-BK7 Schott material, a common choice for its excellent optical properties. The coating on both the front and back surfaces is edm mgf2 std curve, which is known for its superior anti-reflective properties, particularly in the 400-700nm wavelength range.
This lens is ideal for applications that require high-quality imaging and light transmission, such as in photography, astronomy, and machine vision systems.
