38-494-INK 12.0mm Dia. x 25mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-494-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.0mm and a focal length of 25mm, making it suitable for a wide range of applications. The lens is made from the high-quality material n-BK7 Schott, which is renowned for its excellent optical properties.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum, specifically between 400 and 1000nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it an ideal choice for applications that require high light transmission and clarity.
The lens's geometry includes a thickness edge of 1.22mm and a thickness center of 2.7mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The lens's radius of curvature (r1) is 12.92mm, and the back focal length (bfl) is 32.22mm.
