MUMBAI, India, July 30 -- Intellectual Property India has published a patent application (202537090430 A) filed by Changzhou Aac Raytech Optronics Co. , Ltd. on September 22, 2025, for Imaging Optical Lens.
Inventor includes Liu, Weixiao.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
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 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 third lens is defined as f3, a focal length of the sixth lens is defined as f6, an on-axis thickness of the second lens is defined as d3, an on-axis distance from an image-side surface of the second lens to an object-side surface of the third lens is defined as d4, an on-axis thickness of the third lens is defined as d5, a central radius of curvature of the 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 sixth lens is defined as R11, and a central radius of curvature of an image-side surface of the sixth lens is defined as R12, satisfying the following relational expressions: 0.12=f3*d5/(R5+R6)=0.30, 2.20=(R11+R12)/f6=4.00, and 4.00=(d3+d5)/d4=8.50.
