This 38-500 lens, sourced from Edmund Optics, is a plano-convex spherical lens with a diameter of 12.5mm and a focal length of 15mm. The lens is made from n-sf11 Schott material, a high-index glass often used in optical systems due to its excellent optical properties. The lens's geometry includes a 1.3mm edge thickness and a 3.1mm center thickness, providing robustness and durability.
The lens features a VIS-NIR coating on both the front and back surfaces, specifically the 'edm visnir0sp2002000' coating. This coating is designed for the visible and near-infrared spectrum, spanning 400-1000nm, making it suitable for a wide range of applications. The coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the system's overall efficiency.
