Title:
IMAGE-CAPTURE OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/128267
Kind Code:
A1
Abstract:
Provided is an image-capture optical lens (10), containing, in order from the object side to the image side: a first lens (L1) having a negative 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, and a sixth lens (L6) having a positive refractive power; the maximum viewing angle of the camera optical lens (10) is FOV, the radius of curvature of the sixth lens (L6) on the object side is R11, the radius of curvature of the sixth lens (L6) on the image side is R12, 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, and 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; further, the following relational expressions are satisfied: 100.00° ≤ FOV ≤ 135.00°; 2.00 ≤ R11/R12 ≤ 20.00; 0.30 ≤ d2/d4 ≤ 1.00. The image-capture optical lens (10) can achieve high imaging performance while also achieving a low TTL.
