MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202537091365 A) filed by Changzhou Aac Raytech Optronics Co. , Ltd. on September 24, 2025, for Imaging Optical Lens.
Inventors include Si, Congfang; 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. Disclosed is an imaging optical lens, comprising seven lenses in total, which are, sequentially from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens, wherein a central radius of curvature of an object-side surface of the third lens is defined as R5, a central radius of curvature of an image-side surface of the third lens is defined as R6, a central radius of curvature of an object-side surface of the fifth lens is defined as R9, a central radius of curvature of an image-side surface of the fifth lens is defined as R10, a focal length of the first lens is defined as f1, a focal length of the second lens is defined as f2, a focal length of the sixth lens is defined as f6, a focal length of the seventh lens is defined as f7, an on-axis distance from an image-side surface of the first lens to an object-side surface of the second lens is defined as d2, an on-axis distance from an image-side surface of the sixth lens to an object-side surface of the seventh lens is defined as d12, an Abbe number of the first lens is defined as v1, and an Abbe number of the second lens is defined as v2, satisfying the following relational expressions: 1.10=R9/R10=1.90, 1.50=(R5+R6)/(R5-R6)=2.80, 17.00=(f6-f7)/d12=20.00, and 0.17=(v1- v2)*d2/(f1-f2)=0.32.
