Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2022/052267
Kind Code:
A1
Abstract:
A camera optical lens (10). 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) having a positive refractive power, a second lens (L2) having a positive refractive power, a third lens (L3) having a positive refractive power, a fourth lens (L4) having a positive refractive power, a fifth lens (L5) having a negative refractive power, a sixth lens (L6), a seventh lens (L7) having a negative refractive power, an eighth lens (L8) having a positive refractive power, and a ninth lens (L9) 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 focal length of the second lens (L2) is f2, the on-axis thickness of the second lens (L2) is d3, the on-axis distance from the image side surface of the second lens (L2) to the object side surface of the third lens (L3) is d4, and the following relational expression is satisfied: 3.50 ≤ f1/f ≤ 5.00, and 2.50 ≤ d3/d4 ≤ 10.00. The camera optical lens (10) features good optical performance while meeting large-aperture, wide-angle, and ultra-thin design requirements.
