38-457 12.5mm Dia. x 40.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
The 38-457 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a circular base shape with a diameter of 12.5mm and a thickness of 1.23mm at the edge, transitioning to 2.2mm at the center. The effective focal length (EFL) of this lens is 40mm, 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 the visible spectrum (350-700nm). This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
The 38-457 is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its valid weblink status. This lens is a versatile and reliable choice for applications that require a high-performing, visible light lens with a plano-convex geometry.
