Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/184276
Kind Code:
A1
Abstract:
A camera optical lens (10), comprising the following from the object side to the image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4) and a fifth lens (L5); the radius of curvature of an object side surface of the second lens (L2) is R3, the radius of curvature of an image side surface of the second lens (L2) is R4, the radius of curvature of an object side surface of the third lens (L3) is R5, and the radius of curvature of an image side surface of the third lens (L3) is R6; 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 on-axis distance from the image side surface of the third lens (L3) to the object side surface of the fourth lens (L4) is d6; the image height of the camera optical lens (10) is IH, and the total optical length of the camera optical lens (10) is TTL. The following relationships are satisfied: 1.50≤(R5+R6)/(R5-R6); 0.40≤d4/d6≤1.25; 1.00≤TTL/IH≤1.30; and 1.00≤(R3+R4)/(R3-R4)≤2.40. The camera optical lens (10) meets the design requirements for having a large aperture, having a wide angle and being ultrathin while also exhibiting good optical performance.
