67-580 40.0mm Dia. x 400.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type 67-580, with a diameter of 40.0mm and a focal length of 400.0mm. It is sourced from the renowned optical components vendor, Edmund Optics. The lens is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens features a spherical shape, with a front radius of curvature of 51.68mm and a back focal length of 95.39mm. The edge thickness of the lens is 2.97mm, while the center thickness is 7mm, providing a robust structure for various applications.
The lens comes with a standard NIR II coating on both the front and back surfaces. This coating, known as "edm nir-ii std curve", is designed to enhance the lens' performance in the NIR II spectrum, improving transmission and reducing unwanted reflections.
This lens is an excellent choice for applications that require high-quality imaging or light transmission in the NIR II spectrum, such as biomedical imaging, night vision, and optical communication systems.
