Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/128134
Kind Code:
A1
Abstract:
The present invention relates to the field of optical lenses. Disclosed is a camera optical lens, sequentially comprising a first lens having a negative refractive power, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, a fifth lens, a sixth lens, and a seventh lens from an object side to an image side. The maximum field of view of the camera optical lens is FOV, the axial thickness of the first lens is d1, the axial thickness of the second lens is d3, the Abbe number of the second lens is v2, and the Abbe number of the fourth lens is v4; and the following relationships are satisfied: 100.00 ≤ FOV ≤ 135.00, 0.50 ≤ d1/d3 ≤ 1.00, and -20.00 ≤ v2-v4 ≤ -10.00. The camera optical lens provided in the present invention has good optical performance, and also satisfies the design requirements of a wide angle and an ultrathin body.
