48-348 9mm Dia. x -9mm FL; VIS-NIR Coated; Double-Concave Lens 400-1000nm
The 48-348 is a high-quality double-concave lens, boasting a 9mm diameter and a focal length of -9mm. 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 n-SF11 Schott, a material known for its excellent optical properties. It features a geometry that includes a thickness of 3.48mm at the edge and 2.25mm at the center, making it suitable for a wide range of optical applications. The lens's effective focal length (EFL) is -9mm, and it has a back focal length (BFL) of -9.61mm. The radii of curvature for the first and second surfaces are -14.6mm and 14.6mm, respectively.
The 48-348 lens is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance in the visible and near-infrared spectrum, spanning from 400nm to 1000nm. The lens's shape is spherical, a common and versatile geometry in optical systems.
