MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202517088091 A) filed by Changzhou Aac Raytech Optronics Co. on September 16, 2025, for Camera Optical Lens.
Inventor includes Yang, Yongqiang.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: An imaging optical lens (10, 20, 30, 40, 50, 60), composed of a first prism (P1), a first lens (L1) having a negative refractive power, a second lens (L2) having a positive refractive power, a third lens (L3) having a negative refractive power, a fourth lens (L4) having a positive refractive power, and a fifth lens (L5), which are arranged in sequence from an object side to an image side, wherein the first lens (L1) forms a first group, and the second lens (L2), the third lens (L3), the fourth lens (L4) and the fifth lens (L5) form a second group. The second group is movable along an optical axis of the imaging optical lens for adjustment, such that the imaging optical lens (10, 20, 30, 40, 50, 60) is switched between a first state and a second state. A focal length of the imaging optical lens (10, 20, 30, 40, 50, 60) in the first state is defined as fA, and an image height of the imaging optical lens (10, 20, 30, 40, 50, 60) is defined as IH, satisfying the following relational expression: 4.60=fA/IH=4.90. The imaging optical lens (10, 20, 30, 40, 50, 60) can achieve a large- aperture periscopic design and has a good optical performance.
