The 48-783 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, boasting a diameter of 30.0mm and a focal length of 50.0mm. This lens is specifically designed for use within the near-infrared spectrum, between 600-1050nm, making it ideal for a range of applications that require precise optical performance within this wavelength range.
The lens is constructed from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties and durability. The front and back surfaces of the lens are coated with Edmund Optics' NIR I standard curve coating, which is specifically designed to enhance performance within the near-infrared spectrum. 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 is carefully designed to provide optimal performance. The lens has an outer radius of 0mm and an inner radius of 0mm, focusing the light onto a single point. The edge thickness of the lens is 2.82mm, while the center thickness is 6.35mm. The back focal length (BFL) is 46.17mm, and the effective focal length (EFL) is 50mm.
