67-605 6mm Dia. x 24mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-605 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a 6mm diameter and a focal length of 24mm, 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 of the lens is circular, and it features a standard spherical geometry. The radius of curvature for the first surface is 24.36mm, while the second surface has a radius of -24.36mm, indicating its double-convex design.
The lens's edge thickness is 2.23mm, and the center thickness is 2.6mm, providing a robust structure. The effective focal length (EFL) is 24mm, and the back focal length (BFL) is 23.13mm. The lens does not have an inner or outer radius.
The 67-605 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 spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications that require high-quality imaging or light transmission in the NIR range.
