MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202517087682 A) filed by Changzhou Aac Raytech Optronics Co. on September 15, 2025, for Camera Optical Lens.
Inventor includes Li, Pengfei.
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, which consists of a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a negative refractive power and a triangular prism having a negative refractive power, which are arranged in sequence from the object side to the image side. An on-axis distance from the object-side surface of the first lens to the image-side surface of the third lens is D, a total optical length of the camera optical lens is TTL, a focal length of the camera optical lens is f, a refractive index of a glass lens of the camera optical lens is ndi, the sagittal height of the image-side surface of the third lens at the maximum effective optical diameter is SAG32, half of the maximum effective optical diameter of the image-side surface of the third lens is SD32, a focal length of the third lens is f3, an on-axis thickness of the third lens is d5, a radius of curvature of the object-side surface of the third lens is R5, and a radius of curvature of the image-side surface of the third lens is R6, which satisfy the following relational expressions: 0.11=D/TTL=0.20, 0.10=D/f=0.22, 1.49=ndi=1.85, 0.32=|SAG32|/SD32=0.52 and -20.03=f3*d5/(R5-R6)=-7.99.
