MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202517093454 A) filed by Changzhou Aac Raytech Optronics Co. on September 29, 2025, for Imaging Optical Lens.
Inventor includes Yang, Tingting.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The present application relates to the field of optical lenses. Disclosed is a camera optical lens. The camera optical lens comprises seven lenses in total; the seven lenses, successively from an object side to an image side, are: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a negative refractive power, a sixth lens having a positive refractive power, and a seventh lens having a negative refractive power; the focal length of the optical camera lens is f; the total optical length of the optical camera lens is TTL; the field of view of the optical camera lens is FOV; the focal length of the first lens is f1; the focal length of the sixth lens is f6; the focal length of the seventh lens is f7, the radius of curvature of the object-side surface of the third lens is R5; the radius of curvature of the image-side surface of the third lens is R6; the radius of curvature of the object-side surface of the fourth lens is R7; the radius of curvature of the image-side surface of the fourth lens is R8; the following relational expressions are satisfied: 2.40=(f6- f7)/f1=3.20; 0.90=TTL/(f*tan(FOV/2))=1.40; 0.30=R5/R6=0.80; -15.0=(R7+R8)/(R7-R8)=-1.50.
