49-465 9mm Dia. x 13.5mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-465 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 13.5mm. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock. The lens is designed for use within the near-infrared spectrum, specifically between 600-1050nm, making it suitable for a wide range of applications in this wavelength range.
The lens is constructed from N-BK7 Schott glass, a material well-known for its excellent optical properties and versatility. The front and back surfaces of the lens are coated with the EDM NIR-I std curve coating, which is specifically designed to enhance performance within the near-infrared spectrum. This coating aids in reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The lens geometry is characterized by a center thickness of 2.75mm and an edge thickness of 1.2mm. The front and back radii of curvature are 13.46mm and -13.46mm, respectively, resulting in a back focal length of 12.56mm. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
