49-965 20mm Dia. x 30mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 49-965 is a UV Plano-Convex Lens, 20mm in diameter and 30mm in focal length, featuring UV-AR coating on both surfaces. 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 for versatile application. The front surface is coated with EDM UV STD CURVE, while the back surface also features the same coating. This coating enhances the lens's performance within the UV spectrum by reducing unwanted reflections and increasing transmission.
The geometry of the lens includes a 1.69mm thickness at the edge and a 6mm thickness at the center. The inner radius is 0mm, and the outer radius is also 0mm. The lens's effective focal length (EFL) is 30mm, and the back focal length (BFL) is 25.88mm. The radius of curvature (R1) is 13.75mm.
The lens is made from fused sil mal-1965, a material known for its excellent optical properties within the UV spectrum. The wavelength for this item is 587.6nm.
