88-642 6.0mm Dia. x 18.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-642 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 6.0mm and a focal length of 18.0mm, 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, making it ideal for a wide range of applications.
The geometry of the lens is carefully designed with a thickness of 0.92mm at the edge and 1.42mm at the center. The lens's inner and outer radii are 0, indicating a flat surface on one side and a curved surface on the other. The back focal length is 17.07mm, and the effective focal length is 18mm, providing a focused, clear image.
