84-293 30mm Dia. x 60mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm
The 84-293 is a UV Plano-Convex Lens, 30mm in diameter and 60mm focal length, manufactured by Edmund Optics. This lens is designed for use in the ultraviolet spectrum, specifically between 250 and 425nm, as indicated by its UV-AR coating.
The lens is made of fused silica, a material known for its high transparency in the UV range, making it an ideal choice for UV applications. The lens geometry includes a 1.55mm edge thickness and a 6mm center thickness, with a base shape of a circle.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM UV STD curve. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the UV range.
The lens's geometry also includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple spherical shape. The lens's effective focal length (EFL) is 60mm, and the back focal length (BFL) is 55.89mm.
The lens is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. This lens is a reliable and high-performing option for any UV optical system.
