40mm Diameter x 60mm FL Double-Convex Lens with MgF2 Coating from Edmund Optics
This item is a 40mm diameter x 60mm focal length double-convex lens, coated with MgF2 on both surfaces. It is sourced from the reputable optical components vendor, Edmund Optics. The lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens geometry features a double-convex shape, with a 60.56mm radius of curvature on both the front and back surfaces. The lens has a center thickness of 8.8mm and an edge thickness of 2mm. The effective focal length (EFL) is 60mm, and the back focal length (BFL) is 57.1mm. The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and availability.
The lens is coated with MgF2 on both the front and back surfaces, which is a standard coating that provides high transmission across the visible spectrum. This coating helps to reduce surface reflections and increase the overall efficiency of the optical system.
