10.0mm Dia. x 17.5mm FL Plano-Convex Lens by Edmund Optics
This item is a 10.0mm diameter x 17.5mm focal length plano-convex lens, offered by the renowned optical components vendor, Edmund Optics. The lens boasts a VIS-EXT coating on both the front and back surfaces, ensuring optimal performance within the visible spectrum, specifically between 350-700nm.
The lens geometry is characterized by a 1.29mm edge thickness and a 2.8mm center thickness. The radius of curvature (R1) is 9.05mm, and the back focal length (BFL) is 15.66mm. The lens is made of N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion, making it suitable for a wide range of optical applications.
The VIS-EXT coating on this lens is a broadband anti-reflection coating, designed to minimize surface reflections and increase transmission within the visible spectrum. This coating is especially beneficial in applications where high transmission and low loss are critical, such as in imaging systems, beam delivery systems, and laser applications.
