The 88-653-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 9.0mm and a thickness at the edge of 1.56mm. The center thickness is 3.0mm, and the effective focal length (EFL) is 15.0mm. The lens's front radius of curvature (R1) is 7.75mm, and the back focal length (BFL) is 13.02mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with EDM VIS EXT on both the front and back surfaces, a coating designed for use in the visible spectrum, specifically between 350-700nm. This coating enhances the lens's transmission in the visible range, making it ideal for applications that require high light transmission in this spectrum.
