88-622 4.0mm Dia. x 4.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-622 is a Plano-Convex lens, a type of spherical lens with a single curved surface and a flat surface. This lens, sourced from Edmund Optics, has a diameter of 4.0mm and a focal length of 4.0mm, making it a compact and efficient optical component. The lens is made from n-lasf44 Schott, a material known for its excellent optical properties.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to the visual spectrum (350-700nm), is designed to enhance the lens's performance by reducing surface reflections and increasing transmission. The coating ensures that the lens delivers optimal performance in applications that fall within this spectral range.
The geometry of the lens is carefully designed to provide the best possible optical performance. The edge thickness of the lens is 1.0mm, while the center thickness is 1.7mm. The lens's effective focal length (EFL) is 4.0mm, and its back focal length (BFL) is 3.06mm. The radius of curvature of the curved surface is 3.21mm.
