The 45-863 is a high-quality double-convex lens, boasting a 6mm diameter and a focal length of 24mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its "in stock" status on the company's website.
The lens is constructed from Schott's n-BK7 glass, a material known for its excellent optical properties, making it suitable for a wide range of applications. The lens features a double-convex geometry, with radii of curvature of 24.36mm and -24.36mm for the front and back surfaces, respectively. This geometry results in a back focal length of 23.13mm and an effective focal length of 24mm.
The lens is coated with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, which is designed to operate across the visible and near-infrared spectrum, from 400nm to 1000nm. This coating ensures high transmission and low reflectance, enhancing the lens's performance in its intended applications.
