Camera optical lens
View Patent ↗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 having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, and a sixth lens having a negative refractive power. The camera optical lens further satisfies specific conditions.
1. A camera optical lens comprising, from an object side to an image side in sequence: a first lens having a positive refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a negative refractive power, a fifth lens having a positive refractive power, and a sixth lens having a negative refractive power; wherein the camera optical lens further satisfies the following conditions:
1.00≤ f 1/ f≤ 1.10;
0.15≤ f 2/ f 4≤0.16;
−2.40≤( R 1+ R 2)/( R 1− R 2)≤−1.90;

f: the focal length of the camera optical lens;
f1: the focal length of the first lens;
f2: the focal length of the second lens;
f4: the focal length of the fourth lens;
R1: the curvature radius of object side surface of the first lens;
R2: the curvature radius of image side surface of the first lens;
R7: the curvature radius of the object side surface of the fourth lens;
R8: the curvature radius of the image side surface of the fourth lens.
2. The camera optical lens as described in claim 1 , wherein the camera optical lens further satisfies the following conditions:
