MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202517088970 A) filed by Aac Optics Changzhou Co. , Ltd. on September 18, 2025, for Imaging Optical Lens.
Inventor includes Pan, Hongxiang.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: An imaging optical lens (10, 20, 30, 40, 50, 60, 70), consisting of seven lenses, which are, sequentially from an object side to an image side, a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6) and a seventh lens (L7). The focal length of the imaging optical lens (10, 20, 30, 40, 50, 60, 70) is defined as f, the focal length of the seventh lens (L7) is defined as f7, the field angle of the imaging optical lens (10, 20, 30, 40, 50, 60, 70) at a 1.0 field of view is defined as FOV, the image height of the imaging optical lens (10, 20, 30, 40, 50, 60, 70) at a 1.0 field of view is defined as IH, the central radius of curvature of an object-side surface of the sixth lens (L6) is defined as R11, and the central radius of curvature of an image-side surface of the sixth lens (L6) is defined as R12, satisfying the following relational expressions: 3.95=f7/f=6.00, 100.00º=(FOV*f)/IH=120.00º, and 3.50=(R11+R12)/(R11-R12)=70.00. The imaging optical lens (10, 20, 30, 40, 50, 60, 70) has a good optical performance and meets the design requirements of a large aperture and an ultra-wide angle.
