67-664 30mm Dia. x 120mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-664 is a high-performance Double-Convex Lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a 30mm diameter and a focal length of 120mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent transparency in the visible and near-infrared regions. The lens features a double-convex geometry, with radii of curvature of 123.17mm and -123.17mm for the first and second surfaces, respectively. This geometry results in a back focal length of 118.34mm.
The 67-664 lens is coated with Edmund Optics' NIR-II Standard Curve coating on both the front and back surfaces. This coating enhances the lens' performance in the near-infrared region, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
The lens has a thickness of 3.17mm at the edge and 5mm at the center, providing robustness and durability. The lens is circular in shape, allowing for versatile mounting and integration into various optical systems.
