47-853 4.0mm Dia. x 10.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-853 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a 4.0mm diameter and a 10.0mm focal length, 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 plano-convex geometry, meaning one side is flat (plano), and the other side is curved (convex). The radius of curvature for the curved side is 5.19mm, and the back focal length is 8.92mm. The edge thickness of the lens is 1.24mm, while the center thickness is 1.64mm, providing a robust and durable structure.
The 47-853 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible to near-infrared spectrum, specifically between 400-1000nm. This makes it suitable for applications that require broadband light transmission, such as imaging, spectroscopy, and beam shaping.
