63-819 6mm Dia. x 12mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-819 is a high-quality spherical lens, boasting a 6mm diameter and a 12mm focal length, making it a versatile choice for various optical applications. This lens is sourced from the reputable vendor, Edmund Optics, ensuring reliability and performance.
The lens is designed in a double-convex shape, featuring a base shape of a circle. This design allows for a wide range of applications, including imaging and illumination. The geometry of the lens is well-defined, with a thickness edge of 1.34mm and a thickness center of 2.2mm. The effective focal length (EFL) is 12mm, and the radii of curvature are 10.65mm for the first surface and -10.65mm for the second surface. The back focal length (BFL) is 11.23mm.
The lens is constructed from fused silica, specifically identified as fused sil mal-1965 in the material ID. This material is known for its excellent optical properties, making it suitable for use in the visible and near-infrared (VIS-NIR) spectrum, specifically between 400nm and 1000nm.
The lens features a VIS-NIR coating on both the front and back surfaces, identified as edm visnir0sp2002000. This coating enhances the lens's performance in the VIS-NIR spectrum, reducing surface reflections and improving transmission.
