Photographing optical lens system with seven lens elements
A recently granted patent (Publication Number: US11971527B2) discloses a photographing optical lens system comprising seven lens elements arranged in a specific order from the object side to the image side. Each lens element has distinct characteristics, including object-side and image-side surfaces with inflection points, convex and concave regions, and positive refractive power. The system's focal length and various axial distances between lens elements are carefully defined to meet specific conditions, ensuring optimal performance. Additionally, the patent includes detailed specifications for the curvature radius, Abbe numbers, and composite focal lengths of the lens elements to achieve desired imaging results.
Furthermore, the patent extends to an imaging apparatus incorporating the aforementioned lens system and an image sensor, as well as an electronic device with multiple imaging apparatuses facing the same direction. The electronic device features varying angles of view for different imaging apparatuses, enhancing versatility in capturing images. The patent's claims cover a range of technical aspects, including lens element configurations, focal lengths, thickness ratios, and refractive indices, all aimed at improving the overall performance and image quality of the optical lens system. The detailed specifications outlined in the patent provide valuable insights for professionals in the field of photography and optical technology, offering a comprehensive guide for designing advanced imaging systems.
