48-308 25mm Dia. x 100mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
The 48-308 is a UV-AR coated, UV double-convex lens, boasting a 25mm diameter and a 100mm focal length. This lens, sourced from Edmund Optics, is a spherical lens with a convex-convex base shape and a circular geometry. The lens's edge thickness measures 2.06mm, while the center thickness is 3.78mm, providing a solid and robust structure.
The lens's effective focal length (EFL) is 100mm, and its front and back radii are 91.09mm and -91.09mm respectively, contributing to its double-convex design. The back focal length (BFL) is 98.7mm, and the lens has no inner or outer radius, indicating a uniform curvature throughout.
The lens is made from fused sil mal-1965, a material known for its excellent optical properties. It is designed to operate at a wavelength of 587.6nm, making it suitable for a wide range of applications.
The lens features UV-AR coatings on both the front and back surfaces, following the standard EDMM UV curve. This coating enhances the lens's performance in the UV range, specifically between 250-425nm, by reducing unwanted reflections and increasing transmission.
