Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/052271
Kind Code:
A1
Abstract:
A camera optical lens (10), relating to the field of optical lenses. The camera optical lens (10) contains nine lenses in total, and the nine lenses, from object side to image side, are sequentially: 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) having a 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 sixth lens (L6) is d11, the on-axis distance from the image side surface of the sixth lens (L6) to the object side surface of the seventh lens (L7) is d12, and the following relational expression is satisfied: 0.60 ≤ f1/f ≤ 1.80, and 1.50 ≤ d11/d12 ≤ 8.00. The camera optical lens (10) features good optical performance while meeting large-aperture, wide-angle, and ultra-thin design requirements.
