67-582-INK 50.0mm Dia. x 75.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-582-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm and a focal length of 300mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The front and back surfaces of the lens are coated with the EDM NIR-II STD curve coating, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the NIR II range.
The lens has a thickness of 3.7mm at the edge and 5.0mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on the non-curved side of the lens. The back focal length (BFL) is 296.7mm.
The lens is in stock and available for purchase on the Edmund Optics website, as indicated by the "weblink status" field in the item data. This lens is a great option for anyone looking for a high-quality, NIR II compatible Plano-Convex lens for their optical system.
