49-509 50mm Dia. x 100mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-509 is a high-quality double-convex lens, boasting a 50mm diameter and a 100mm focal length. This lens is sourced from the reputable optical vendor, Edmund Optics, and is readily available for your optical system needs.
The lens is fabricated from the well-known glass material, n-BK7 Schott, which is renowned for its excellent optical properties. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 101.63mm for the first surface and -101.63mm for the second surface. This geometry results in a back focal length of 96.65mm.
The lens has a thickness of 3.76mm at the edge and 10mm at the center, providing robustness and durability. The effective focal length (EFL) of the lens is 100mm, making it suitable for a wide range of applications.
The 49-509 lens is coated with the EDM NIR-I std curve on both the front and back surfaces. This coating enhances its performance in the near-infrared spectrum, specifically between 600nm and 1050nm. This makes the lens an excellent choice for applications such as thermal imaging, spectroscopy, and other NIR-based technologies.
