45-864 6mm Dia. x 30mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-864 is a high-quality double-convex lens, boasting a 6mm diameter and a 30mm focal length. 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 vendor's website.
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 spherical geometry, with a center thickness of 2.3mm and an edge thickness of 2mm. The effective focal length (EFL) of the lens is 30mm, and the back focal length (BFL) is 29.23mm. The radii of curvature for the first and second surfaces are 30.61mm and -30.61mm, respectively.
The lens is coated with a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating is designed to optimize the lens's performance in the visible and near-infrared spectrum, specifically between 400nm and 1000nm. This makes the lens suitable for a wide range of applications, including but not limited to, imaging, spectroscopy, and beam shaping.
