This is a 5.0mm diameter, plano-convex lens with a focal length of 20.0mm, designed for use within the visible light spectrum (425-675nm). The lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from n-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and high Abbe number. The plano-convex shape, where one side is flat and the other curved, is a common configuration for lenses, providing a simple yet effective means of focusing or dispersing light.
The lens features a standard anti-reflective coating on both the front and back surfaces, designed for 0-degree incidence angle within the visible spectrum. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
The geometry of the lens includes an outer radius of 0mm, an inner radius also of 0mm, and a thickness at the center of 1.5mm. The edge thickness is slightly less at 1.19mm. The lens's effective focal length (EFL) is 20.0mm, and the radius of curvature (R1) is 10.34mm.
