48-313 25mm Dia. x 300mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
The 48-313 is a UV-AR coated, UV double-convex lens, boasting a 25mm diameter and a focal length of 300mm. This lens, sourced from the reputable vendor Edmund Optics, is designed for use within the UV spectrum, specifically between 250-425nm.
The lens's geometry is characterized by a 2.52mm edge thickness and a 3.09mm center thickness, with a back focal length of 298.94mm. The base shape is circular, and the lens features a spherical design, with radii of curvature of 274.6mm and -274.6mm for the first and second surfaces, respectively. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
The lens is constructed from fused silica, identified as mal-1965 in the material database. This material is known for its excellent transparency in the UV region, making it an ideal choice for this lens. The lens is coated with a UV-AR coating on both the front and back surfaces, following the standard curve as defined by Edmund Optics. This coating enhances the lens's performance within the UV spectrum by reducing surface reflections and increasing transmission.
