49-906 9.0mm Dia. x 15.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This 49-906 optical lens, sourced from Edmund Optics, is a Plano-Convex Spherical Lens with a 9.0mm diameter and a focal length of 15.0mm. The lens is made from N-BK7 Schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a front and back coating of EDM NIR-I STD Curve, providing excellent transmission and reflection properties within the near-infrared spectrum, specifically between 600-1050nm. This coating enhances the lens's performance in NIR applications, such as thermal imaging, spectroscopy, and night vision systems.
The lens's geometry includes a thickness of 1.56mm at the edge and 3mm at the center, with an effective focal length (EFL) of 15mm. The radius of curvature for the first surface (R1) is 7.75mm, and the back focal length (BFL) is 13.02mm. The lens's base shape is circular, and it does not have any inner or outer radius specifications.
