89-144 10mm Dia. x 20mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a 10mm diameter, double-convex lens with a focal length of 20mm, 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 350nm 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 illumination systems.
The lens's geometry includes a thickness of 1.25mm at the edge and 2.5mm at the center, with a back focal length of 19.16mm. The radii of curvature for the first and second surfaces are 20.24mm and -20.24mm, respectively. The lens's design, coupled with its high-quality material and coating, ensures excellent image quality and light transmission.
