49-496 25mm Dia. x 150mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-496 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a 25mm diameter and a focal length of 150mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott, a popular optical glass known for its excellent transparency and low dispersion. This material ensures high-quality imaging and minimal chromatic aberration. The lens features a standard NIR I coating on both the front and back surfaces, enhancing its performance in the near-infrared spectrum (600-1050nm). This coating improves transmission, reduces reflection, and increases the lens's overall durability.
The geometry of the lens is meticulously designed, with an inner radius of 0mm and an outer radius of 0mm. The edge thickness measures 2.39mm, while the center thickness is 3.4mm. The back focal length is 148.88mm, and the radius of curvature for the first and second surfaces are 154.52mm and -154.52mm, respectively.
