The 38-467-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens features a front and back coating of EDM VIS EXT, which is a broadband anti-reflection coating designed for use in the visible spectrum. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens has a thickness of 1.39mm at the edge and 2.5mm at the center. The effective focal length (EFL) of the lens is 50mm, and the radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 48.35mm, and the lens does not have an inner or outer radius.
This lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. It is a crown glass with a low refractive index and low dispersion, making it an ideal choice for many optical systems.
