67-586 50.0mm Dia. x 175.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens, with a circular base shape, sourced from the renowned optical vendor, Edmund Optics. The lens boasts a 50.0mm diameter and a 175.0mm focal length, making it suitable for a wide range of applications.
The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transmission in the visible and near-infrared regions. The lens has a refractive index of 1.5168 at 587.6nm, contributing to its high-performance optical capabilities.
The lens features a plano-convex geometry, with a 3.55mm edge thickness and a 10mm center thickness. The front and back surfaces are coated with Edmund Optics' NIR-II standard curve coating, designed to enhance transmission in the near-infrared spectrum, specifically between 750nm and 1550nm. This coating ensures optimal performance in applications that utilize near-infrared light.
The lens's inner and outer radii are 0, indicating a sharp transition between the lens surface and the surrounding medium. The effective focal length (EFL) of the lens is 100mm, contributing to its high-performance optical capabilities.
