The 48-801 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a 50.0mm diameter and a 200.0mm focal length, making it a substantial addition to any optical system. The lens is crafted from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a standard NIR I coating on both the front and back surfaces, enhancing its performance within the 600-1050nm wavelength range. This coating is designed to improve the lens's transmission and reduce reflection, thereby optimizing its efficiency and functionality in near-infrared applications.
The geometry of the lens is meticulously designed, with an edge thickness of 2mm and a center thickness of 5.07mm. The lens's inner and outer radii are 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 200mm, and its back focal length (BFL) is 196.66mm, providing a clear understanding of its optical characteristics.
