48-727-INK 9.0mm Dia. x 18.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 48-727-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 focal length of 18.0mm, denoted as FL in the item data.
The lens's geometry includes a thickness of 1.25mm at the edge and 2.41mm at the center. The front surface has a radius of curvature of 9.32mm, and the back focal length is 16.41mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens's coating, both front and back, is Edmund Optics' standard NIR I coating, designed for use in the near-infrared spectrum. This coating enhances the lens's performance in this specific range, making it ideal for applications such as thermal imaging, spectroscopy, and other near-infrared-based technologies.
