This is a Plano-Convex lens, type 47-353-INK, sourced from Edmund Optics. The lens has a base shape of a circle and is designed for use in the visible light spectrum, specifically between 425-675nm. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The lens has a diameter of 25.0mm and a thickness at the edge of 2.63mm, while the center thickness is 3.5mm. The effective focal length (EFL) of the lens is 175.0mm, and the radius of curvature (R1) is 90.47mm. The back focal length (BFL) is 172.85mm, and the lens does not have an inner or outer radius.
The lens features a standard VIS-0 coating on both the front and back surfaces, designed to provide high transmission across the visible spectrum. This coating is part of Edmund Optics' standard curve series, ensuring consistent performance and quality.
Please note that the lens is inked, which is a common practice in the industry to mark lenses for identification and tracking purposes. This does not affect the lens's optical performance.
