88-709 20.0mm Dia. x 20.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-709 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 20.0mm, making it a compact and efficient optical component. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to Edmund Optics, is designed to enhance transmission in the visible spectrum, specifically between 350-700nm. The coating ensures high-quality image transmission, minimizing light loss and improving overall system performance.
The geometry of the lens is well-defined, with a thickness of 1mm at the edge and 4.6mm at the center. The lens's effective focal length (EFL) is 20mm, and its back focal length (BFL) is 17.42mm. The lens's inner and outer radii are 0mm, indicating a plano surface on one side and a curved surface on the other.
