The 48-758-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 20.0mm and a focal length of 30.0mm, making it suitable for a variety of optical applications. The lens is made from N-BAF10 Schott, a high-quality optical material known for its excellent transmission properties in the near-infrared (NIR) region.
The lens features a standard NIR I coating on both the front and back surfaces, which is specifically designed to enhance its performance in the 600-1050nm wavelength range. This coating helps to reduce surface reflections 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 an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 1.84mm and a thickness at the center of 4.5mm. The back focal length (BFL) is 27.3mm, and the effective focal length (EFL) is 30.0mm. The lens is inked, which is a process that adds a marking or identifier to the lens for easy identification and tracking.
