MUMBAI, India, July 30 -- Intellectual Property India has published a patent application (202537087495 A) filed by Changzhou Aac Raytech Optronics Co. , Ltd. on September 15, 2025, for Photographing Optical Lens.
Inventors include Liu, Yuyi; and Zhou, Shunda.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: Disclosed in the present invention is a photographing optical lens, comprising five lenses in total. The five lenses successively comprise, from an object side to an image side: a first lens having positive refractive power, a second lens having negative refractive power, a third lens having negative refractive power, a fourth lens having negative refractive power, and a fifth lens having positive refractive power. An axial distance from an image-side surface of the second lens to an object-side surface of the third lens is d4; an axial distance from an image-side surface of the third lens to an object-side surface of the fourth lens is d6; a central curvature radius of an object-side surface of the second lens is R3; a central curvature radius of an image-side surface of the second lens is R4; a central curvature radius of an object- side surface of the fifth lens is R9; and a central curvature radius of an image-side surface of the fifth lens is R10. The following relational expressions are satisfied: 3.00=d6/d4=6.00; -2.00=R9/R10=-0.80; and 1.70=(R3+R4)/(R3-R4)=2.50.
