WIPO Patent Application WO/2022/052261
Kind Code:
A1
Abstract:
Disclosed is a camera optical lens (10). The camera optical lens (10) comprises nine lenses in total, and the nine lenses are sequentially from the object side to the image side: a first lens (L1), a second lens (L2) having positive refractive power, a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), an eighth lens (L8), and a ninth lens (L9). The focal length of the camera optical lens (10) is f, the focal length of the first lens (L1) is f1, the on-axis thickness of the seventh lens (L7) is d13, the on-axis distance from the image side surface of the seventh lens (L7) to the object side surface of the eighth lens (L8) is d14, and the following relational expressions are satisfied: 3.50≤f1/f≤6.50; 3.00≤d13/d14≤15.00. The camera optical lens (10) has a good optical performance, and also satisfies large-aperture, wide-angle, and ultra-thin design requirements.
