LA1708-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm 400-1100nm
The LA1708-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, sourced from Thorlabs. This lens is designed for use in the 400-1100nm wavelength range, making it suitable for a wide range of optical applications. The lens has a focal length (EFL) of 200mm, which is the distance from the lens's center to the point at which light rays converge.
The lens's geometry includes a 2mm thickness at the edge and a 2.8mm thickness at the center. The front surface of the lens has a radius of curvature (R1) of 103mm, while the back surface is planar. The lens's inner and outer radii are both 0mm, indicating a uniform curvature.
The LA1708-AB lens is coated with THo AB Bbar on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, thereby improving the overall efficiency of the optical system.
