Classification: CPC G | IPC G

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

−48.31≤f3/f≤3.44;

−1.39≤(R5+R6)/(R5−R6)≤16.47; and

0.02≤d5/TTL≤0.13,

where f denotes a focal length of the camera optical lens, 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.
