67-464-INK 6.0mm Dia. x 18.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type Spherical, with a circular base shape, sourced from the renowned optical 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 has a diameter of 6.0mm and a thickness at the edge of 0.92mm, which gradually increases to 1.42mm at the center. The Effective Focal Length (EFL) is 18.0mm, making it suitable for a variety of optical applications. The lens's front and back surfaces are coated with the "edm nir-ii std curve" coating, enhancing its performance in the NIR II spectrum.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on the lens's entry side. The radius of curvature (R1) is 9.3mm, and the back focal length (BFL) is 17.07mm.
This lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is inked, which is a process often used to enhance the lens's performance or to mark it for identification purposes.
