88-657 9.0mm Dia. x 36.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-657 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 36.0mm, 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 wavelengths between 350-700nm. 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 1.75mm at the edge and 2.3mm at the center. The lens's effective focal length (EFL) is 36mm, and its back focal length (BFL) is 34.48mm. The lens's inner and outer radii are both 0mm, indicating a plano surface on one side and a curved surface on the other.
