This is a Plano-Convex Lens, sourced from the renowned optical component vendor, Edmund Optics. The lens has a diameter of 25.0mm and a focal length of 200.0mm, making it suitable for a wide range of optical applications. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens features a NIR I coating on both the front and back surfaces. This coating, standard from Edmund Optics, is designed to enhance the lens' performance in the near-infrared spectrum, specifically between 600-1050nm. The coating helps to reduce surface reflections, thereby improving transmission and increasing the overall efficiency of the optical system.
The geometry of the lens includes a thickness of 2.44mm at the edge and 3.2mm at the center. The lens's inner and outer radii are both zero, indicating a simple spherical shape. The lens's effective focal length (EFL) is 200.0mm, and the back focal length (BFL) is 197.89mm. The radius of curvature (R1) of the convex surface is 103.36mm.
