This is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It features a base shape of a circle and is designed for use with a 980nm wavelength. The lens has a diameter of 50.0mm and a focal length of 500.0mm, making it suitable for a variety of optical applications.
The lens geometry includes a thickness edge of 3.79mm and a thickness center of 496.7mm. The effective focal length (EFL) is 500.0mm, and the radius of curvature (R1) is 258.4mm. The back focal length (BFL) is also 496.7mm, and both the inner and outer radii are 0mm.
The lens is made from n-BK7 Schott, a high-quality optical glass. It features a laser V-coat coating on both the front and back, specifically designed for 980nm. This coating enhances the lens's performance in laser applications, providing improved durability and efficiency.
