10mm Diameter x 25mm FL NIR I Coated Double-Convex Lens
This is a 10mm diameter x 25mm focal length NIR I coated double-convex lens, available from Edmund Optics. The lens is designed with a double-convex geometry, featuring a base shape of a circle for broad applicability.
The lens has a diameter of 10mm and a thickness at the edge of 1.51mm, while the center thickness is 2.5mm. The effective focal length (EFL) is 25mm, and the first radius of curvature (R1) is 25.41mm, with the second radius of curvature (R2) being -25.41mm. The back focal length (BFL) is 24.16mm, and both the inner and outer radii are 0mm.
The lens is made of N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The coating on both the front and back is EDM NIR-I std curve, designed for the near-infrared spectrum (600-1050nm). This coating enhances the lens's performance in the NIR region, making it suitable for applications such as thermal imaging, night vision, and spectral analysis.
