48-837 12mm Dia. x 35mm; UV-VIS Coated; UV Double-Convex Lens UV-VIS 250-700nm
The 48-837 is a UV-VIS coated, UV double-convex lens, boasting a diameter of 12mm and a thickness of 35mm. This lens, sourced from the reputable vendor Edmund Optics, is designed for use within the UV-VIS spectrum, specifically between 250-700nm.
The lens's geometry is characterized by an edge thickness of 2.1mm and a center thickness of 3.29mm, with an effective focal length (EFL) of 45mm. The first and second radii of curvature (R1 and R2) are 31.57mm and -31.57mm respectively, contributing to a back focal length (BFL) of 43.96mm. The lens's inner and outer radii are both zero, indicating a circular base shape.
The lens is constructed from fused silica, identified as mal-1965 in the Material ID. This material is known for its excellent transparency and durability, making it suitable for a wide range of optical applications.
The lens features a UV-VIS coating on both the front and back surfaces, adhering to the standard curve as defined by Edmund Optics. This coating enhances the lens's performance within the UV-VIS spectrum, reducing losses and improving transmission.
