45-880 15mm Dia. x 22.5mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-880 is a high-quality double-convex lens, 15mm in diameter and with a focal length of 22.5mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use within the visible to near-infrared spectrum, spanning 400-1000nm, making it suitable for a wide range of applications.
The lens boasts a geometry that includes an edge thickness of 2.54mm and a center thickness of 4.2mm. The front and back radii of curvature are 34.36mm and -34.36mm respectively, contributing to an effective focal length of 22.5mm and a back focal length of 21.29mm. The lens is constructed from n-SF11 Schott, a material well-known for its excellent optical properties.
The 45-880 lens features a VIS-NIR coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to enhance the lens' performance within the visible to near-infrared spectrum, reducing surface reflections and increasing transmission.
