48-976 12mm Dia. x 30mm FL; VIS 0deg Coated; UV Double-Convex Lens VIS 0deg 425-675nm
The 48-976 is a high-quality double-convex lens, boasting a 12mm diameter and a 30mm focal length. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its valid in-stock weblink status.
The lens is constructed from fused silica, a material with the material ID 'fused sil mal-1965'. This material is known for its excellent transparency and resistance to thermal shock, making it an ideal choice for a wide range of optical applications.
The 48-976 lens features a spherical shape, with a front and back coating of 'edm vis-0 std curve'. This coating is designed to provide superior performance within the visible light spectrum, specifically between 425 and 675 nanometers.
The lens's geometry is precisely engineered, with an edge thickness of 2.17mm and a center thickness of 3.52mm. The lens's effective focal length (EFL) is 30mm, while its back focal length (BFL) is 28.77mm. The first and second radii of curvature (R1 and R2) are 26.94mm and -26.94mm, respectively.
