34-193 40mm Dia. x 200mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a 40mm diameter, double-convex lens with a focal length of 200mm, sourced from the renowned optical component vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a VIS-EXT coating on both the front and back surfaces, which extends its usable wavelength range from 350 to 700nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it suitable for a wide range of applications, including imaging and laser systems.
The lens's geometry is characterized by a thickness of 6.05mm at the edge and 8mm at the center, with a back focal length of 197.35mm. The radii of curvature for the first and second surfaces are 205.35mm and -205.35mm, respectively. The lens's design, coupled with its high-quality material and coating, ensures excellent image quality and light transmission.
