88-628 4.5mm Dia. x 9.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
This is a 4.5mm diameter, 9.0mm focal length plano-convex lens, sourced from the reputable optical components vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties.
The lens features a plano-convex geometry, where one side is flat, and the other side is curved. This particular lens has a radius of curvature of 4.65mm on the curved side. The lens's edge thickness is 1.8mm, while the center thickness measures 2.38mm, providing a solid structure for various applications.
The lens is 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 lens's effective focal length (EFL) is 9mm, making it suitable for applications that require a compact, high-performance lens. The lens's inner and outer radii are both zero, indicating a uniform curvature across the lens's surface.
