88-664 10.0mm Dia. x 20.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-664 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 10.0mm and a focal length of 20.0mm, making it a compact yet powerful optical component. 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 front and back coating of EDM VIS EXT, a specialized coating that extends the visible range of the lens to 350-700nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving image quality and brightness.
The geometry of the lens is meticulously designed, with a thickness of 1.71mm at the edge and 3.0mm at the center. The lens's inner and outer radii are 0mm, and its base shape is circular. The lens's effective focal length (EFL) is 20.0mm, and its back focal length (BFL) is 18.03mm. The lens's front radius of curvature is 10.34mm.
