49-258 9mm Dia. x 13.5mm; UV-VIS Coated; UV Double-Convex Lens UV-VIS 250-700nm
The 49-258 is a UV-VIS coated, UV double-convex lens with a diameter of 9mm and a center thickness of 3.3mm. This lens, sourced from Edmund Optics, is designed for use within the UV-VIS spectrum, specifically between 250-700nm. The lens features a standard curve coating on both the front and back surfaces, providing excellent transmission and protection against UV and visible light.
The lens has an effective focal length (EFL) of 13.5mm, making it suitable for a variety of optical applications. The first and second radii of curvature are 11.84mm and -11.84mm respectively, contributing to the lens's double-convex shape. The back focal length (BFL) is 12.32mm, and the lens has no inner or outer radius, indicating a uniform thickness.
The material ID for this lens is fused sil mal-1965, which is a type of fused silica known for its high transmittance and durability. The lens's base shape is circular, and it has a thickness edge of 1.52mm. This lens is currently in stock, as indicated by its weblink status.
