Patent ID: 11966018

Abstract:
Provided is a camera optical lens, including, from object side to image side, a first lens having positive refractive power; a second lens having positive refractive power; a third lens having positive refractive power; a fourth lens having negative refractive power; a fifth lens having positive refractive power; a sixth lens; a seventh lens having positive refractive power; an eighth lens having negative refractive power; and a ninth lens having negative refractive power. The camera optical lens satisfies 2.00≤f1/f≤3.50 and 2.00≤d5/d6≤9.00, where f denotes a focal length of the camera optical lens, f1 denotes a focal length of the first lens, d5 denotes an on-axis thickness of the third lens, and d6 denotes an on-axis distance from an image side surface of the third lens to an object side surface of the fourth lens. The lens has large aperture, wide angle and ultra-thinness while having good optical performance.
