Camera lens group with wide field-of-view and low distortion
The granted patent US12072474B2 describes a camera lens group designed to achieve a wide field of view (FOV) exceeding 133.0 degrees while maintaining distortion levels below 25.0%. The lens group consists of seven lenses arranged sequentially along the optical axis, each with specific refractive powers and surface geometries. The first lens has negative refractive power with a convex object-side surface and a concave image-side surface. The subsequent lenses include a mix of positive and negative refractive powers, with various surface curvatures, ensuring that all surfaces are positioned at or adjacent to the optical axis. The claims detail specific relationships between the radii of curvature and effective focal lengths of the lenses, which are critical for optimizing optical performance.
Additional claims provide further constraints on the lens design, including specific ratios involving the radii of curvature and effective focal lengths of certain lenses. These parameters are intended to refine the optical characteristics of the lens group, enhancing its performance in terms of image quality and distortion control. The patent outlines a comprehensive framework for lens design, emphasizing the importance of precise measurements and relationships between the components to achieve the desired optical outcomes. This innovative lens configuration may have applications in various imaging technologies, particularly where wide-angle views are essential.
