34-180 40.0mm Dia. x 80.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm
This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 34-180, boasts a diameter of 40.0mm and a focal length of 80.0mm, making it a versatile choice for various optical applications.
The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for use in the visible spectrum, specifically between 350-700nm.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, short for Visible Extended, is designed to enhance the lens's performance in the visible spectrum. It reduces surface reflections, thereby increasing transmission and improving overall image quality.
The geometry of the lens is also noteworthy. It has an inner radius of 0mm, indicating a flat surface on one side, and an outer radius of 0mm, suggesting a curved surface on the other. The thickness at the edge is 2.84mm, while at the center, it measures 8mm. The back focal length is 74.73mm, and the radius of curvature of the curved surface is 41.34mm.
