38-365-INK 12.5mm Dia. x 100.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 38-365-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. The lens has a front focal length (FFL) of 100.0mm, making it suitable for a variety of optical applications.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The radius of curvature for the curved side is 51.68mm. The lens has a thickness of 1.22mm at the edge and 1.6mm at the center. The back focal length (BFL) is 98.95mm, and the effective focal length (EFL) is also 100mm.
The lens is made from N-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties and wide transparency range. The lens is coated with Edmund Optics' NIR-I standard curve coating on both the front and back surfaces, enhancing its performance in the NIR spectrum.
The lens is inked, a process that involves applying a dye to the edge of the lens to indicate its orientation. This is particularly useful in applications where the lens may be installed in a confined space or where the orientation of the lens is critical.
