SLB-25.4B-50PM 25.4 mm Dia. x 50.8 mm FL; Coated; Double-Convex Lens 400-700nm
This is a high-quality double-convex lens from OptoSigma, designed for use in the visible light spectrum, specifically between 400-700nm. The lens, identified as SLB-25.4B-50PM, has a base shape of a circle and is made from the renowned material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens has a diameter of 25.4mm and a thickness at the edge of 1.9mm, while the center thickness is 5.1mm. The effective focal length (EFL) of this lens is 50.8mm, making it suitable for a wide range of optical applications. The first radius of curvature (R1) is 51.9mm, and the second radius (R2) is -51.9mm, indicating the double-convex nature of the lens. The back focal length (BFL) is 49.2mm.
The lens features anti-reflective coatings on both the front and back surfaces, specifically Opt M coatings. These coatings are designed to minimize reflection and increase transmission, thereby enhancing the performance of the lens in its intended application.
