63-671 15mm Dia. x 20mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 63-671 is a high-quality double-convex lens, 15mm in diameter and 20mm in focal length, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use within the visible to near-infrared spectrum, spanning 400 to 1000nm, making it suitable for a wide range of optical applications.
The lens geometry features a center thickness of 3.5mm and an edge thickness of 1.63mm, with a base shape of a circle. The front and back radii of curvature are 30.6mm and -30.6mm respectively, contributing to a back focal length of 18.99mm. The lens is made from n-SF11 Schott, a popular material known for its excellent optical properties.
The 63-671 lens is coated with a VIS-NIR coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating enhances the lens's performance within the specified wavelength range, reducing surface reflections and increasing transmission.
