45-718-INK 50.0mm Dia. x 150.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-718-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically between 400-1000nm. The lens has a front ( convex ) radius of 77.52mm and a back focal length of 144.07mm.
The lens's geometry includes a thickness edge of 4.86mm and a thickness center of 9mm. The effective focal length (EFL) is 150.0mm. The lens is inked, a process that adds a layer of ink to the edges of the lens to prevent stray light.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with edm visnir0sp2002000 on both the front and back, a coating designed for high transmission in the VIS-NIR range.
This lens is a great option for applications that require a high-quality lens in the VIS-NIR spectrum, such as spectroscopy, biomedical imaging, and machine vision.
