Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 7:
8. The camera optical lens as described in claim 1, wherein the camera optical lens satisfies:

0.41≤f7/f≤1.40;

0.26≤(R13+R14)/(R13−R14)≤1.12; and

0.04≤d13/TTL≤0.12,

where f denotes a focal length of the camera optical lens, f7 denotes a focal length of the seventh 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, d13 denotes an on-axis thickness of the seventh 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.
