45-491-INK 15.0mm Dia. x 15.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-491-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens's geometry is characterized by its edge thickness of 2.16mm and center thickness of 5.5mm. The effective focal length (EFL) is 15.0mm, and the radius of curvature (R1) is 10.09mm. The back focal length (BFL) is 11.71mm, and both the inner and outer radii are 0mm.
The lens is made from n-SF5 Schott, a material known for its excellent optical properties. It is coated with edm visnir0sp2002000 on both the front and back surfaces, enhancing its performance in the VIS-NIR spectrum.
This lens is available for purchase directly from the Edmund Optics website, and the link provided indicates that it is currently in stock.
