This is a 10mm diameter x 50mm focal length Vis-NIR coated double-convex lens, available from Edmund Optics. The lens is designed with a base shape of a circle and features a geometry that includes an edge thickness of 2.01 and a center thickness of 2.5. The effective focal length (EFL) is 50, with a front radius (R1) of 51.25 and a back radius (R2) of -51.25. The back focal length (BFL) is 49.17.
The lens is made from n-BK7 Schott material, a popular choice for its high transmission in the visible and near-infrared regions. The lens is coated with edm visnir0sp2002000 on both the front and back, a Vis-NIR anti-reflection coating designed for high transmission in the 400-1000nm range.
This lens is a spherical lens, specifically a double-convex lens, which means it has two spherical surfaces that are both convex. This design is often used to collimate or focus light, making it suitable for a wide range of applications in imaging, beam shaping, and laser systems.
