67-530 18.0mm Dia. x 72.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, type 67-530, with a diameter of 18.0mm and a focal length of 72.0mm, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from the reputable optical vendor, Edmund Optics.
The lens is made from the high-quality material n-SF5, produced by Schott, ensuring excellent optical performance. The lens features a plano-convex geometry, meaning one side is flat while the other is curved, which is beneficial for a variety of applications.
The lens has a center thickness of 3.8mm and an edge thickness of 1.41mm, providing a solid structure. The effective focal length (EFL) is 27mm, and the radius of curvature (R1) is 18.16mm. The back focal length (BFL) is 24.73mm, and the lens does not have an inner or outer radius.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, optimized for the wavelength of 587.6nm. This coating enhances the lens's performance in the NIR spectrum, specifically between 750nm and 1550nm.
