This is a 50.0mm diameter x 500.0mm focal length Plano-Convex lens, offered by Edmund Optics. The lens is made from n-BK7 Schott material, a popular choice for its excellent optical properties and versatility.
The lens features a YAG-BBAR coating on both the front and back surfaces, specifically designed for the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for applications that require high light transmission and minimal loss.
The lens's geometry includes a thickness edge of 3.79mm and a thickness center of 5mm. The radius of curvature (R1) is 258.4mm, and the back focal length (BFL) is 496.7mm. The lens's shape is spherical, and it has no inner or outer radius.
