47-387 25.0mm Dia. x 500.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-387 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 25.0mm diameter and a 500.0mm focal length, making it suitable for a wide range of 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 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, thereby improving the overall efficiency and quality of the optical system.
The geometry of the lens includes a thickness of 2.9mm at the edge and 3.2mm at the center. The radius of curvature (R1) is 258.4mm, and the back focal length (BFL) is 497.89mm. The lens's shape is spherical, and it has no inner or outer radius, indicating a uniform curvature across the lens surface.
The lens's information is currently valid and in stock, according to the vendor's website. This availability status and the detailed specifications provided here should assist users in their search for optical components with similar properties.
