88-658 9.0mm Dia. x 45.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm

The 88-658 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 45.0mm, making it suitable for a wide range of 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 is designed to extend the visible range of the lens, making it suitable for use in the 350-700nm wavelength range. The coating also helps to reduce surface reflections, improving the overall efficiency and performance of the lens.

The geometry of the lens includes a thickness of 1.1mm at the edge and 1.54mm at the center. The inner and outer radii are both 0mm, indicating a flat surface on the uncoated side of the lens. The effective focal length (EFL) is 45.0mm, and the back focal length (BFL) is 43.98mm.
