45-475-INK 9.0mm Dia. x 13.5mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-475-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically between 400-1000nm. The lens has a front ( convex) radius of curvature of 9.09mm and a back (plano) radius of curvature of infinity.
The lens has an effective focal length (EFL) of 13.5mm, which is the distance from the lens's principal point to its focal point. The lens's thickness at the edge is 1.4mm, while its center thickness is 2.6mm. The back focal length (BFL), the distance from the lens's rear principal point to its focal point, is 11.94mm.
The lens is made from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties in the VIS-NIR range. The lens's surfaces are coated with edm visnir0sp2002000, a broadband antireflection coating that enhances its transmission in the VIS-NIR spectrum.
This lens is inked, a process that involves applying a dye to the lens's edge to indicate its orientation. The ink color and location can vary depending on the vendor's specific practices.
