The 88-686-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, 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 VIS-EXT coating on both the front and back surfaces, which is Edmund Optics' proprietary broadband anti-reflection coating. This coating is designed to minimize surface reflections and increase transmission in the visible spectrum, enhancing the overall performance of the lens.
The geometry of the lens includes a thickness of 1.94mm at the edge and 5.25mm at the center, with an effective focal length (EFL) of 15mm. The lens's front surface has a radius of curvature of 7.75mm, and the back focal length (BFL) is 11.53mm. The lens is made from N-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties and wide transparency range.
