38-478 35.0mm Dia. x 35.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
The 38-478 is a Plano-Convex Spherical Lens, sourced from the reputable optical vendor, Edmund Optics. This lens, with a base shape of Circular, is designed for use within the visible light spectrum, specifically optimized for wavelengths of 587.6nm.
The lens boasts a diameter of 35.0mm, with a thickness at the edge of 1.7mm and a center thickness of 8.0mm. The effective focal length (EFL) is 35.0mm, and the radius of curvature (R1) is 27.47mm. The back focal length (BFL) is 30.52mm, and both the inner and outer radii are 0mm, indicating a plano surface on the incident side.
The lens is constructed from n-SF11 Schott, a high-index glass with 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 within the visible spectrum (350-700nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.
