Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/134286
Kind Code:
A1
Abstract:
A camera optical lens (10, 20, 30, 40, 50, 60), comprising, in order from an object side to an image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), and a sixth lens (L6). At least one of the first lens (L1) to the sixth lens (L6) comprises a free-form surface. The total focal length of the camera optical lens (10, 20, 30, 40, 50, 60) is f, the focal length of the third lens (L3) is f3, the on-axis distance from the image side surface of the first lens (L1) to the object side surface of the second lens (L2) is d2, 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 expressions are satisfied: -8.00≤f3/f≤-3.00; and 0.00≤d2/d4≤4.00. The camera optical lens (10, 20, 30, 40, 50, 60) satisfies large-aperture, wide-angle and ultra-thin design requirements while having good optical properties.
