MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202537091481 A) filed by Changzhou Aac Raytech Optronics Co. , Ltd. on September 24, 2025, for Optical Imaging Lens.
Inventors include Zhou, Xuepeng; and Zhou, Shunda.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present application relates to the field of optical lenses, and discloses an optical imaging lens. The optical imaging lens comprises seven lenses in total, the seven lenses being sequentially arranged from an object side to an image side and comprising: 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, wherein a focal length of the fourth lens is f4, a focal length of the fifth lens is f5, a focal length of the sixth lens is f6, a focal length of the seventh lens is f7, a center curvature radius of an object-side surface of the fifth lens is R9, a center curvature radius of an image-side surface of the fifth lens is R10, and the optical imaging lens satisfies the following relationship: 0.50 = f4/f5 = 1.20; -7.00 = R10/R9 = -1.00; and -1.60 = f6/f7 = -1.10.
