Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/031240
Kind Code:
A1
Abstract:
The present invention provides a camera optical lens. The camera optical lens sequentially comprises, 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 refractive power, a fourth lens having refractive power, a fifth lens having positive refractive power, and a sixth lens having negative refractive power. The focal length of the camera optical lens is f, the focal length of the second lens is f2, the thickness of the first lens on an axis is d1, the distance from the image side surface of the first lens to the object side surface of the second lens on the axis is d2, the radius of curvature of the third lens at the image side surface is R6, the radius of curvature of the fifth lens at the object side surface is R9, the radius of curvature of the fifth lens at the image side surface is R10, and the following relations are satisfied: -3.50≤f2/f≤-1.50; 6.50≤d1/d2≤13.50; -0.20≤(R9+R10)/(R9-R10)≤-0.05; 3.00≤R6/f≤10.00. The camera optical lens of the present invention can satisfy the design requirements for large aperture, ultra-thinness, and wide angle while having good optical performance.
