CAMERA OPTICAL LENS

WIPO Patent Application WO/2022/057035

A1

A camera optical lens (10), including a total of six lenses, which from the object side to the image side are sequentially: a first lens (L1) having a positive refractive power, a second lens (L2) having a negative refractive power, a third lens (L3) having a negative refractive power, a fourth lens (L4) having a negative refractive power, a fifth lens (L5) having a positive refractive power, and a sixth lens (L6) having a negative refractive power. The focal length of the camera optical lens (10) is f, the focal length of the second lens (L2) is f2, the central curvature radius of the object side surface of the third lens (L3) is R5, the central curvature radius of the image side surface of the third lens (L3) is R6, the central curvature radius of the object side surface of the fifth lens (L5) is R9, the central curvature radius of the image side surface of the fifth lens (L5) is R10, the on-axis thickness of the third lens (L3) is d5, the on-axis distance from the image side surface of the third lens (L3) to the object side surface of the fourth lens is d6, and the following relationships are satisfied: -2.50≤f2/f≤-1.20; 3.50≤(R5+R6)/(R5-R6)≤12.00; 4.00≤R10/R9; 0.50≤d5/d6≤1.20. The camera optical lens (10) has ultra-thin, wide-angle and large-aperture features.
