88-682 12.0mm Dia. x 72.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-682 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 72.0mm, making it a versatile choice 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 the visual spectrum (350-700nm), enhances the lens's transmission capabilities and reduces surface reflections. The front surface has a radius of curvature of 37.21mm, while the back surface is planar, contributing to the lens's plano-convex shape.
The lens's geometry includes an edge thickness of 1.91mm and a center thickness of 2.4mm. The back focal length (BFL) is 70.42mm, and the effective focal length (EFL) is 72mm. The lens's design is circular, and it does not have any inner or outer radii.
