45-861 6mm Dia. x 12mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-861 is a high-quality double-convex lens, boasting a 6mm diameter and a 12mm focal length. This lens is sourced from the reputable vendor, Edmund Optics, and is designed for use within the visible to near-infrared spectrum, spanning 400-1000nm.
The lens is constructed from Schott's n-BK7 glass, a material renowned for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens ideal for applications that require high image quality and minimal chromatic aberration.
The 45-861 features a front and back coating of edm visnir0sp2002000, a proprietary anti-reflective coating developed by Edmund Optics. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image contrast.
The lens's geometry is meticulously designed, with an edge thickness of 1.64mm and a center thickness of 2.4mm. The front and back radii of curvature are 11.98mm and -11.98mm, respectively, resulting in a back focal length of 11.18mm. The lens's shape is spherical, ensuring a consistent curvature across the entire surface.
