47-480 6mm Dia. x 12mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-480 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. This lens boasts a 6mm diameter and a 12mm focal length (FL), making it suitable for a wide range of optical applications. The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating is designed to enhance the lens' performance in the visible light spectrum, particularly between 425 and 675nm. The coating reduces surface reflections, thereby improving light transmission and enhancing the overall image quality.
The geometry of the lens is also noteworthy. The lens has an outer radius of 0mm, indicating a flat outer surface, and an inner radius of 0mm, suggesting a curved inner surface. The center thickness of the lens is 2.4mm, while the edge thickness is 1.64mm. The back focal length (BFL) is 11.18mm, and the effective focal length (EFL) is 12mm.
The lens's R1 and R2 parameters, which represent the radii of curvature of the first and second surfaces, are 11.98mm and -11.98mm, respectively. These parameters, along with the lens's geometry and material, contribute to its overall optical performance.
