88-679 12.0mm Dia. x 48.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-679 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.0mm and a focal length of 48.0mm, making it a versatile option for various optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to Edmund Optics, is designed to enhance the lens's performance in the visible spectrum, specifically between 350-700nm. The coating reduces surface reflections, improving transmission and overall image quality.
The geometry of the lens is also noteworthy. The edge thickness measures 1.76mm, while the center thickness is 2.5mm. The lens's effective focal length (EFL) is 48mm, and the radius of curvature (R1) is 24.82mm. The back focal length (BFL) is 46.36mm, and both the inner and outer radii are 0mm.
