45-489-INK 12.0mm Dia. x 84.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-489-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.0mm and a focal length of 84.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and chemical resistance.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared regions of the spectrum, specifically from 400 to 1000nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
The geometry of the lens includes a thickness of 2.08mm at the edge and 2.5mm at the center. The inner and outer radii are both 0mm, indicating a flat inner surface and a curved outer surface. The lens's effective focal length (EFL) is 84.39mm, and the back focal length (BFL) is 82.39mm.
The lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the weblinks section.
