MUMBAI, India, Aug. 24 -- Intellectual Property India has published a patent application (202514103410 A) filed by Zhejiang Sunny Optics Co. , Ltd. on October 27, 2025, for Optical Imaging Lens Assembly.
Inventors include Zhang, Xin; Bao, Shicheng; Song, Litong; Li, Weifang; Huang, Lin; and Zhao, Liefeng.
The application for the patent was published on August 21, 2026, under issue no. 34/2026.
Abstract: The present application discloses an optical imaging lens assembly, including a lens group and a spacer element group. The lens group sequentially includes, from an object side to an image side along an optical axis: a first lens having a negative power, a second lens having a negative power, a third lens having a positive power, a fourth lens having a positive power, a fifth lens having a negative power, and a sixth lens having a positive power. The spacer element group includes a fourth spacer element and a fifth spacer element. The optical imaging lens assembly satisfies: 2.77(D4m-d4m)/CT54.67 and 6.40EP45/T4510.26; where D4m is an outer diameter of an image side surface of the fourth spacer element, d4m is an inner diameter of the image side surface of the fourth spacer element, CT5 is a central thickness of the fifth lens on the optical axis, EP45 is a distance from the image side surface of the fourth spacer element to an object side surface of the fifth spacer element in a direction of the optical axis, and T45 is a spacing distance between the fourth lens and the fifth lens on the optical axis.
