67-603 6mm Dia. x 12mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-603 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global provider of optical components. This lens boasts a 6mm diameter and a focal length of 12mm, making it suitable for a wide range of applications.
The lens is constructed from N-BK7 Schott glass, a popular material due to its excellent optical properties and versatility. The base shape is circular, and the lens features a standard spherical geometry. The center thickness of the lens is 2.4mm, while the edge thickness is 1.64mm, providing a robust and durable structure.
The 67-603 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 spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
The lens has an effective focal length (EFL) of 12mm and a back focal length (BFL) of 11.18mm. The first radius of curvature (R1) is 11.98mm, and the second radius (R2) is -11.98mm. The inner and outer radii are both 0mm, indicating a uniform curvature.
