45-879 15mm Dia. x 15mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-879 is a high-quality double-convex lens, 15mm in diameter and featuring a focal length of 15mm, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use within the visible to near-infrared spectrum (VIS-NIR), catering to wavelengths between 400 and 1000 nanometers.
The lens boasts a sophisticated geometry, with a thickness of 1.93mm at the edge and 4.5mm at the center, making it an ideal choice for various applications. The front and back surfaces of the lens are coated with edm visnir0sp2002000, a proprietary anti-reflective coating developed by Edmund Optics, further enhancing its performance within the VIS-NIR spectrum.
The lens's base shape is circular, and its design incorporates two convex surfaces with radii of curvature of 22.51mm and -22.51mm, respectively. This spherical shape ensures excellent light gathering and focusing capabilities. The back focal length (BFL) of the lens is 13.68mm, and it has no inner or outer radius, indicating a uniform curvature across the lens surface.
