63-686 30mm Dia. x 100mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
This is a high-quality double-convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, identified as 63-686, has a diameter of 30mm and a focal length of 100mm, making it suitable for a wide range of applications.
The lens is made from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and chemical resistance. The base shape of the lens is circular, and it features a double-convex geometry with radii of curvature of 102.5mm and -102.5mm for the first and second surfaces, respectively.
The lens's edges have a thickness of 2.79mm, while the center thickness is 5mm. The effective focal length (EFL) is 100mm, and the back focal length (BFL) is 98.34mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.
The lens is coated with Edmund Optics' 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 (VIS) and near-infrared (NIR) regions, specifically between 400nm and 1000nm.
