47-850 4.0mm Dia. x 4.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-850 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts 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 front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum, specifically between 400 and 1000nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it ideal for applications that require high-quality imaging or light transmission.
The lens's geometry includes a thickness of 1.0mm at the edge and 1.7mm at the center, providing a balanced profile for efficient light transmission. The lens's inner and outer radii are 0, indicating a flat surface on the lens's non-curved side. The effective focal length (EFL) is 4.0mm, and the back focal length (BFL) is 3.06mm, which are crucial specifications for designing optical systems.
