38-377-INK 25.4mm Dia. x 40.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 38-377-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 25.4mm and a focal length of 40mm, making it suitable for a variety of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature for the curved side is 20.67mm, and the lens has a central thickness of 5.9mm and an edge thickness of 1.54mm. The back focal length (BFL) is 36.11mm, and the effective focal length (EFL) is 40mm.
The 38-377-INK lens is coated with Edmund Optics' NIR-I standard curve coating on both the front and back surfaces. This coating is designed for the near-infrared (NIR) region, specifically for wavelengths between 600nm and 1050nm. This coating enhances the lens's performance in the NIR region by reducing reflection and increasing transmission.
