Classification: CPC G | IPC G

Claim 3:
4. The camera optical lens as described in claim 1, the camera optical lens satisfies following conditions:

0.78≤f3/f≤3.42;

−7.90≤(R5+R6)/(R5−R6)≤−1.83; and

0.03≤d5/TTL≤0.11,

where
f3 denotes a focal length of the third lens;
R5 denotes a central curvature radius of an object side surface of the third lens;
R6 denotes a central curvature radius of an image side surface of the third lens;
d5 denotes an on-axis thickness of the third lens; and
TTL denotes a total optical length from an object side surface of the first lens to an image plane of the camera optical lens along an optic axis.
