88-698-INK 15.0mm Dia. x 40.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-698-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 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 1.59mm at the edge and 3.0mm at the center. The effective focal length (EFL) of the lens is 40.0mm, which is the distance over which the lens forms a parallel (collimated) beam when a point source is placed at its front focal point.
The lens's front surface has a radius of curvature of 20.67mm, while the back focal length (BFL) is 38.02mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
