Patent ID: 11644648

Abstract:
The present disclosure relates to the technical field of optical lens and discloses a camera optical lens. The camera optical lens includes, from an object side to an image side: a first lens, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens, a fifth lens and a sixth lens. And the camera optical lens satisfies following conditions: 2.00≤f1/f2≤5.00 and 2.00≤R3/R4≤4.50, where f1 denotes a focal length of the first lens; f2 denotes a focal length of the second lens; R3 denotes a curvature radius of an object-side surface of the second lens; and R4 denotes a curvature radius of an image-side surface of the second lens. The camera optical lens of the present disclosure can achieve a high imaging performance while obtaining a low TTL.
