67-471 6.0mm Dia. x 72.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

The 67-471 is a Plano-Convex lens with a diameter of 6.0mm and a focal length of 72.0mm, specifically designed for use in the Near-Infrared II (NIR II) spectrum, covering the wavelength range of 750-1550nm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry.

The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The Plano-Convex geometry, where one side is flat and the other is curved, is ideal for a wide range of applications, including imaging and beam shaping.

The 67-471 features a front and back coating of EDM NIR-II STD CURVE, which is designed to enhance performance in the NIR II spectrum. This coating helps to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the optical system.

The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature. The edge thickness is 1.42mm, while the center thickness is 1.6mm, providing a good balance between weight and optical performance. The effective focal length (EFL) is 48mm, which is a common choice for many optical systems due to its compact size and wide range of applications.
