49-261 12mm Dia. x 24mm; UV-VIS Coated; UV Double-Convex Lens UV-VIS 250-700nm
This 49-261 UV-VIS coated, UV double-convex lens, with a diameter of 12mm and a thickness of 1.39mm at the edge and 3.1mm at the center, is a high-quality optical component designed for use in the ultraviolet-visible (UV-VIS) spectrum, specifically between 250 and 700nm. The lens, sourced from the reputable vendor Edmund Optics, is a spherical lens with a base shape of a circle and a focal length of 24mm.
The lens's geometry is characterized by its inner and outer radii, both of which are 0mm, and its back focal length of 22.92mm. The front and back surfaces of the lens are coated with the standard UV-VIS coating from Edmund Optics, which enhances its performance in the UV-VIS range.
This lens is made of fused silica, a material with the material ID 1965, which is known for its excellent optical properties, including high transparency and resistance to thermal shock. The lens's shape is spherical, with radii of curvature of 21.51mm and -21.51mm for the first and second surfaces, respectively.
