67-172-INK 9.0mm Dia. x 72.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 67-172-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use in the near-infrared spectrum, specifically between 600-1050nm, as indicated by its NIR I coating. The lens has a front focal length (FFL) of 72.0mm and a back focal length (BFL) of 70.68mm, providing a long focal length for various optical applications.
The lens's geometry includes a thickness edge of 1.73mm and a thickness center of 2.0mm, indicating a slight curvature. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The coating on both the front and back of the lens is Edmund Optics' standard NIR-I curve, designed to enhance performance in the near-infrared spectrum.
This lens is inked, a process that typically involves the application of a dye or paint to the lens to indicate specific information such as the vendor, part number, or coating type. The inking process can also enhance the lens's visibility and handling, making it easier to identify and use in complex optical systems.
