88-768-INK 50.0mm Dia. x 500.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-768-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, is designed for use within the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens features a front and back coating of EDM VIS EXT, which is a broadband anti-reflection coating designed for use in the visible spectrum. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens has a thickness of 3.79mm at the edge and 5.0mm at the center. It has an effective focal length (EFL) of 500.0mm, which is the distance from the lens's principal point to the focal point when the lens is focused at infinity. The lens's back focal length (BFL) is 496.7mm, which is the distance from the lens's rear surface to its focal point when the lens is focused at infinity.
The lens is made from N-BK7 Schott, a common type of optical glass known for its excellent optical properties and high homogeneity. The lens's inner and outer radii are 0mm, indicating that it is a plano-convex lens, where one surface is flat, and the other is curved.
