Abstract
The present disclosure discloses a camera optical lens. The camera optical lens including, in an order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The camera optical lens further satisfies specific conditions.
Claims11
A camera optical lens comprising, from an object side to an image side in sequence:
- a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens;
- wherein the camera optical lens satisfies the following conditions:
- 1<=f1/f<=1.5;
- 1.7<=n7<=2.2;
- −2<=f3/f4<=2;
- −10<=(R13+R14)/(R13−R14)<=10;
- 0.01<=d13/TTL<=0.05;
- where
- f:
- a focal length of the camera optical lens;
- f1:
- a focal length of the first lens;
- f3:
- a focal length of the third lens;
- f4:
- a focal length of the fourth lens;
- n7:
- a refractive index of the seventh lens;
- d13:
- a thickness on-axis of the seventh lens;
- TTL:
- a total distance from an object side surface of the first lens to an image surface along an optic axis;
- R13:
- a curvature radius of object side surface of the seventh lens;
- R14:
- a curvature radius of image side surface of the seventh lens.
