65-291 1.0mm Dia. x 1.5mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 65-291 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 1.0mm and a focal length of 1.5mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm.
The lens is made from n-lasf9 Schott, a material known for its excellent optical properties. It features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating designed for the visible to near-infrared range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission.
The lens's geometry includes a thickness of 0.7mm at the edge and 0.8mm at the center. The inner and outer radii are 0, indicating a flat surface on one side and a curved surface on the other. The effective focal length (EFL) is 1.5mm, and the back focal length (BFL) is 1.07mm.
The lens's information, including web links, is valid and indicates that it is currently in stock, making it readily available for your optical needs.
