63-650 20mm Dia. x 80mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 63-650 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global provider of optical components. This lens boasts a 20mm diameter and a focal length of 80mm, making it suitable for a wide range of applications.
The lens is constructed from n-BK7 Schott, a popular optical glass due to its excellent transparency in the visible and near-infrared regions. The base shape of the lens is circular, and it features a standard spherical geometry. The radius of curvature for the first surface is 82mm, while for the second surface it is -82mm, indicating a double-convex design. The lens has an edge thickness of 2.78mm and a center thickness of 4mm.
The 63-650 lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is specifically designed for the 600-1050nm near-infrared range, enhancing the lens's performance in this spectrum. The coating reduces reflection and increases transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
