Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/047995
Kind Code:
A1
Abstract:
Provided by the present invention is a camera optical lens, which comprises five lenses in total. The five lenses comprise, in order from the object side to the image side, a first lens that has a positive refractive power, a second lens that has a negative refractive power, a third lens that has a negative refractive power, a fourth lens that has a positive refractive power and a fifth lens that has a negative refractive power. The overall focal length of the camera optical lens is f, the focal length of the first lens is f1, the focal length of the third lens is f3, the radius of curvature of the object side surface of the second lens is R3, the radius of curvature of the image side surface of the second lens is R4, the radius of curvature of the object side surface of the third lens is R5, the radius of curvature of the image side surface of the third lens is R6, the on-axis thickness of the fourth lens is d7, and the on-axis distance from the image side surface of the fourth lens to the object side surface of the fifth lens is d8, which satisfy: 0.70≤f1/f≤0.90; -35.00≤f3/f≤-10.00; 4.00≤R3/ R4≤12.00; 3.00≤(R5+R6)/(R5-R6)≤20.00; and 2.00≤d7/d8≤4.50. The camera optical lens has good optical performance, and also meets the design requirements for wide angle and ultra-thinness.
