This is a 10.0mm diameter, 40.0mm focal length plano-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, and features a VIS-EXT coating on both the front and back surfaces.
The lens's geometry includes a thickness of 2.39mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 40.0mm. The radius of curvature for the first surface (R1) is 20.67mm, and the back focal length (BFL) is 38.02mm. The lens's design is spherical, and it does not have any inner or outer radius specifications.
The VIS-EXT coating on the lens enhances its performance in the visible spectrum, specifically between 350-700nm. This coating is designed to increase transmission while reducing reflection, making it ideal for applications that require high light transmission and minimal loss due to reflection.
