38-378-INK 25.4mm Dia. x 75.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 38-378-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.4mm, is designed for use in the near-infrared spectrum, specifically between 600-1050nm. The lens features a front and back coating of EDM NIR-I std curve, providing enhanced performance in the specified wavelength range.
The lens has a center thickness of 3.5mm and an edge thickness of 1.36mm, contributing to its overall profile. The effective focal length (EFL) of this lens is 75mm, and its radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 72.69mm, and the lens does not have an inner or outer radius.
This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is inked, which is a process that adds a layer of ink to the edge of the lens to indicate the orientation. This is particularly useful during assembly to ensure the correct orientation of the lens.
