49-912 20.0mm Dia. x 35.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens has a diameter of 20.0mm and a focal length of 35.0mm, making it suitable for a wide range of optical applications. The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties.
The lens features a NIR I coating on both the front and back surfaces, which is standard for Edmund Optics. This coating is designed to enhance the lens' performance in the near-infrared region, specifically between 600 and 1050nm. The coating helps to reduce reflection and increase transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.
The geometry of the lens includes a thickness of 1.48mm at the edge and 4.5mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the uncoated side of the lens. The radius of curvature of the coated surface is 18.09mm, and the back focal length is 32.04mm.
