Patent ID: 11209611

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. The camera optical lens satisfies following conditions: 3.50≤f1/f≤7.00 and −20.00≤R9/d9≤−17.00, where f denotes a focal length of the camera optical lens; f1 denotes a focal length of the first lens; R9 denotes a curvature radius of an object-side surface of the fifth lens; and d9 denotes an on-axis thickness of the fifth lens. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
