84-289 15mm Dia. x 45mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 84-289 is a UV Plano-Convex Lens, 15mm in diameter and 45mm focal length, manufactured by Edmund Optics. This lens is designed for use in the ultraviolet spectrum, specifically between 250 and 425nm. The lens is made from fused silica, a material known for its high transparency in the UV range.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The curved side has a radius of curvature of 20.63mm, and the lens has a central thickness of 3mm and an edge thickness of 1.59mm. The lens's effective focal length (EFL) is 45mm, and its back focal length (BFL) is 42.94mm.
The 84-289 is coated with Edmund Optics' standard UV coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the UV range by reducing reflection and increasing transmission. The coating curve is not specified, but it is standard for UV applications.
