The 38-455 is a Plano-Convex Spherical Lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a circular base shape with a diameter of 12.5mm and a thickness of 1.29mm at the edge, transitioning to 2.4mm at the center. The effective focal length (EFL) of this lens is 35mm, making it suitable for a wide range of optical applications.
The lens is fabricated from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The front and back surfaces of the lens are coated with EDM VIS-EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350-700nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall image quality.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on the non-curved side. The curvature of the lens is defined by a radius of 18.09mm on the curved side. The back focal length (BFL) of the lens is 33.42mm.
