89-417 5mm Dia x 20mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 89-417 is a UV Plano-Convex Lens, 5mm in diameter and 20mm in focal length, featuring UV-AR coating on both sides. This lens, sourced from Edmund Optics, is designed for use within the UV spectrum, specifically between 250-425nm.
The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a 5mm diameter, a 1.15mm edge thickness, and a 1.5mm center thickness. The effective focal length (EFL) is 20mm, and the back focal length (BFL) is 18.97mm. The lens is made from fused silica, identified as mal-1965 in the material database.
The lens features UV-AR coating on both the front and back surfaces, following the standard curve as defined by Edmund Optics. This coating is designed to reduce unwanted reflections and increase transmission within the UV spectrum.
Please note that the inner and outer radii of the lens are both 0, indicating a flat inner surface and a curved outer surface. This specific lens is a Plano-Convex lens, meaning one side is flat while the other side is curved.
