Image capturing lens assembly with seven lens elements
The patent US12044829B2 describes an innovative image capturing lens assembly consisting of seven lens elements arranged sequentially along an optical path. Each lens element features distinct surface characteristics, with specific refractive powers and curvatures. Notably, the second lens element is convex on the object-side and concave on the image-side, while the fourth and fifth elements have convex image-side surfaces. The assembly includes various conditions related to axial distances, central thicknesses, and focal lengths of the lens elements, ensuring optimal optical performance. The design incorporates aspheric surfaces with inflection points, enhancing image quality and reducing optical aberrations.
Additionally, the patent outlines specific configurations and relationships between the lens elements, such as the focal lengths and distances between them, which are critical for achieving desired imaging characteristics. The assembly is designed to be integrated into imaging apparatuses, which include an image sensor positioned on the image surface of the lens assembly. Furthermore, the patent extends to electronic devices that utilize this imaging apparatus, indicating its potential applications in consumer electronics and advanced imaging systems. The detailed claims emphasize the technical specifications and performance criteria that contribute to the assembly's functionality and effectiveness in capturing high-quality images.
