67-606 6mm Dia. x 30mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-606 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 30mm, 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 optical properties and versatility. The base shape is circular, and the lens features a standard spherical shape, with radii of curvature of 30.61mm for the first surface and -30.61mm for the second surface. This design ensures a high level of optical performance and minimal aberrations.
The lens has a thickness of 2mm at the edge and 2.3mm at the center, providing robustness and durability. The effective focal length (EFL) is 30mm, and the back focal length (BFL) is 29.23mm. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens.
The 67-606 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as NIR imaging, spectroscopy, and sensing.
