Abstract
A camera optical lens is provided and includes, from an object side to an image side, a first lens to a ninth lens. Each of the first lens, the second lens, the fourth lens, the sixth lens, the seventh lens, and the eighth lens has a positive refractive power, and each of the third lens, the fifth lens, and the ninth lens has a negative refractive power. The camera optical lens satisfies following conditions: 3.50≤f1/f≤7.00; and 2.00≤d11/d12≤9.00, where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, d11 denotes an on-axis thickness of the sixth lens, and d12 denotes an on-axis distance from an image side surface of the sixth lens to an object side surface of the seventh lens. The camera optical lens meets design requirements for large aperture, wide angle and ultra-thinness while achieving good optical performance.
