48-042 12mm Dia. x 30mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
The 48-042 is a UV-AR coated, double-convex lens with a diameter of 12mm and a focal length of 30mm, sourced from the reputable optical vendor, Edmund Optics. This lens is designed for use within the UV spectrum, specifically between 250-425nm, making it an ideal choice for applications such as UV imaging or spectroscopy.
The lens features a standard UV coating on both the front and back surfaces, adhering to Edmund Optics' standard curve. This coating enhances the lens's performance within the UV spectrum by reducing unwanted reflections and increasing transmission. The lens's geometry includes an edge thickness of 2.17mm and a center thickness of 3.52mm, contributing to its overall robustness and durability.
The lens's base shape is circular, and its geometry is spherical, with radii of curvature of 26.94mm and -26.94mm for the first and second surfaces, respectively. The back focal length (BFL) is 28.77mm, and the effective focal length (EFL) is 30mm. The lens is made from fused silica, a material with a high transmission rate across a wide range of wavelengths, including the UV spectrum.
