88-635-INK 5.0mm Dia. x 25.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-635-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, as indicated by its VIS-EXT coating. The lens has a base shape of a circle and is inked for easy identification and handling.
The lens's geometry includes a thickness of 1.36mm at the edge, increasing to 1.6mm at the center, and an effective focal length (EFL) of 25mm. The radius of curvature for the first surface (R1) is 12.92mm, and the back focal length (BFL) is 23.95mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The VIS-EXT coating on both the front and back surfaces of the lens enhances its performance in the visible light spectrum. This coating reduces reflection and increases transmission, making it ideal for applications that require high light transmission and minimal reflection.
