Classification: CPC G | IPC G

Claim 0:
1. A camera optical lens, comprising from an object side to an image side:
a first lens;
a second lens having negative refractive power;
a third lens;
a fourth lens;
a fifth lens;
a sixth lens;
a seventh lens;
an eighth lens; and
a ninth lens,
wherein the camera optical lens satisfies following conditions:

0.70≤f1/f≤1.80;

−10.0≤(R13+R14)/(R13−R14)≤−6.00; and

2.00≤d15/d16≤10.00,

where
f denotes a focal length of the camera optical lens;
f1 denotes a focal length of the first lens;
R13 denotes a central curvature radius of an object side surface of the seventh lens;
R14 denotes a central curvature radius of an image side surface of the seventh lens;
d15 denotes an on-axis thickness of the eighth lens; and
d16 denotes an on-axis distance from an image side surface of the eighth lens to an object side surface of the ninth lens.
