The 45-860 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 6mm diameter and a 9mm focal length, making it suitable for a wide range of applications.
The lens is constructed from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 8.91mm and -8.91mm for the first and second surfaces, respectively. The lens has an edge thickness of 1.22mm and a center thickness of 2.25mm, contributing to its robustness and durability.
The 45-860 lens is coated with Edmund Optics' VIS-NIR coating, specifically the edm visnir0sp2002000 coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible and near-infrared regions of the spectrum, specifically between 400nm and 1000nm. This makes the lens ideal for applications that require broadband light transmission, such as imaging, spectroscopy, and beam shaping.
