Document Type and Number:
WIPO Patent Application WO/2022/052263
Kind Code:
A1
Abstract:
A camera optical lens (10), the camera optical lens (10) comprising nine lenses in total. In order from the object side to the image side, the nine lenses are: a first lens (L1), a second lens (L2), 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 second lens (L2) has negative refractive power. 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 fourth lens (L4) is d7, the on-axis distance from the image side surface of the fourth lens (L4) to the object side surface of the fifth lens (L5) is d8, and the following relationships are satisfied: 0.60≤f1/f≤1.50; and 2.50≤d7/d8≤12.00. The camera optical lens (10) satisfies design requirements for a large aperture, a wide angle and ultra-thinness while having a good optical performance.
