MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202514105413 A) filed by Zhejiang Sunny Optics Co. , Ltd. on October 31, 2025, for Optical Imaging Lens.
Inventors include Huan Li; and Jiayu Cai.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: An optical imaging lens is provided, including a lens barrel, a lens group, and a spacer element group. The lens group and the spacer element group are disposed in the lens barrel. The lens group includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens disposed in sequence along an optical axis from an object side to an image side. The spacer element group includes a first spacer element and a second spacer element. An object-side surface of the first lens is convex, an image-side surface of the first lens is concave, an object-side surface of the second lens is convex, and an image-side surface of the second lens is convex. The optical imaging lens meets following relationships: 0.80 R2 / R1 2.95 and 0.75 R1 / R3 × (d1s / d2s) 4.05. R1 represents a radius of curvature of the object-side surface of the first lens, R2 represents a radius of curvature of the image-side surface of the first lens, R3 represents a radius of curvature of the object-side surface of the second lens, d1s represents a maximum inner size of an object-side surface of the first spacer element along a direction perpendicular to the optical axis, and d2s represents a maximum inner size of an object-side surface of the second spacer element along the direction perpendicular to the optical axis.
