67-180 9.0mm Dia. x 72.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 67-180 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a 9.0mm diameter and a focal length of 72.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it an ideal choice for applications that require high-quality imaging or light transmission.
The geometry of the lens includes a thickness edge of 1.73mm and a thickness center of 2mm. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's base shape is circular, adding to its versatility in various applications.
The lens's EFL (Effective Focal Length) is 72mm, and the BFL (Back Focal Length) is 70.68mm. The R1 (Radius of Curvature) is 37.21mm. These specifications provide a clear picture of the lens's optical properties, aiding users in their selection process.
