63-828 12mm Dia. x 15mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-828 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a 12mm diameter and a 15mm focal length, making it suitable for a wide range of applications.
The lens is constructed from fused silica, a material known for its excellent optical properties, including high transparency across a broad spectrum. This particular lens is designed to transmit light in the visible and near-infrared regions, specifically between 400 and 1000 nanometers.
The 63-828 lens features a UV coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission. The coating is of the type "edm visnir0sp2002000", a proprietary coating developed by Edmund Optics, ensuring high-quality performance and durability.
The lens geometry is spherical, with a center thickness of 4.5mm and an edge thickness of 1.57mm. The front and back radii of curvature are 13.01mm and -13.01mm, respectively, resulting in a back focal length of 13.37mm. The lens is designed to be used in air, with an effective focal length of 15mm.
