MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202517092066 A) filed by Changzhou Aac Raytech Optronics Co. on September 25, 2025, for Camera Optical Lens.
Inventors include Xing, Siyuan; and Zhou, Shunda.
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 an imaging optical lens. The imaging optical lens comprises five lenses in total, the five lenses being, sequentially from an object side to an image side, 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 positive refractive power, and a fifth lens having a negative refractive power, wherein a focal length of the imaging optical lens is defined as f, a focal length of the first lens is defined as f1, a radius of curvature of an object-side surface of the third lens is defined as R5, a radius of curvature of an image-side surface of the third lens is defined as R6, an on-axis distance from an image-side surface of the fifth lens to an image surface is defined as BF, the total optical length of the imaging optical lens is defined as TTL, a radius of curvature of an object-side surface of the fifth lens is defined as R9, and a radius of curvature of the image-side surface of the fifth lens is defined as R10, satisfying the following relational expressions: 1.30=f1/f=1.50, -0.60=(R5+R6)/(R5-R6)=-0.35, 0.27=BF/TTL=0.34, and 2.10=R9/R10=2.70.
