45-893 25mm Dia. x 125mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-893 is a high-quality double-convex lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a 25mm diameter and a focal length of 125mm, making it suitable for a wide range of applications.
The lens is crafted from N-BK7 Schott glass, a popular material due to its excellent optical properties and versatility. The base shape is circular, and the lens features a double-convex geometry, with radii of curvature of 128.65mm and -128.65mm for the first and second surfaces, respectively. This geometry results in a back focal length of 123.84mm.
The 45-893 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, between 400 and 1000nm.
The lens has a thickness of 2.28mm at the edge and 3.5mm at the center, providing robustness and durability. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface.
