45-497-INK 18.0mm Dia. x 54.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-497-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front (convex) radius of 27.91mm and a back focal length of 52.02mm, resulting in an effective focal length of 54.0mm.
The lens is inked, a process that adds a layer of ink to the surface of the lens to enhance its visibility under certain conditions. The ink used in this process is specifically designed to not interfere with the lens's optical properties.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for a wide range of applications, particularly where high image quality and low distortion are required.
The lens is coated with edm visnir0sp2002000, a broadband anti-reflection coating designed for use in the visible to near-infrared spectrum. This coating reduces surface reflections, improving transmission and enhancing the overall performance of the lens.
