Document Type and Number:
WIPO Patent Application WO/2022/052270
Kind Code:
A1
Abstract:
The present invention relates to the field of optical lenses, and disclosed is a camera optical lens. The camera optical lens comprises nine lenses in total. In order from the object side to the image side, the nine lenses are: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens and a ninth lens. The second lens has negative refractive power. The focal length of the camera optical lens is f, the focal length of the first lens is f1, the on-axis thickness of the seventh lens is d13, the on-axis distance from the image side surface of the seventh lens to the object side surface of the eighth lens is d14, and the following relationships are satisfied: 0.90≤f1/f≤2.00; and 2.50≤d13/d14≤12.00. The camera optical lens provided in the present invention satisfies design requirements for a large aperture, wide angle and ultra-thinness while having a good optical performance.
