49-988 6mm Dia. x 24mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
The 49-988 is a UV-AR coated, UV double-convex lens, boasting a 6mm diameter and a 24mm 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 1.58mm, while the center thickness is 2mm, providing a solid and robust structure.
The lens's effective focal length (EFL) is 24mm, and its first and second radii of curvature (R1 and R2) are 21.69mm and -21.69mm respectively, contributing to its double-convex design. The back focal length (BFL) is 23.31mm, and both the inner and outer radii are 0mm, indicating a uniform curvature.
The lens is made from fused silica, identified as mal-1965 in the Material ID, a common material for optical lenses due to its high transparency and resistance to thermal shock. The wavelength of 587.6nm suggests this lens is designed for use in the visible light spectrum.
The lens features UV-AR coatings on both the front and back surfaces, following the standard curve as specified by Edmund Optics. This coating enhances the lens's performance in the UV range, specifically between 250-425nm, making it ideal for UV applications.
