20mm Diameter x 60mm FL NIR I Coated Double-Convex Lens
This is a 20mm diameter x 60mm focal length NIR I coated double-convex lens, available from Edmund Optics. The lens is designed with a double-convex spherical shape, featuring a base shape of a circle.
The lens has a center thickness of 4mm and an edge thickness of 2.36mm. The effective focal length (EFL) is 60mm, and the back focal length (BFL) is 58.67mm. The first radius of curvature (R1) is 61.33mm, and the second radius of curvature (R2) is -61.33mm. The inner radius is 0mm, and the outer radius is also 0mm.
The lens is made of N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties. The lens is coated with Edmund Optics' standard NIR-I coating on both the front and back surfaces, designed for the 600-1050nm wavelength range. This coating enhances the lens' performance in the near-infrared spectrum.
