Title:
CAMERA OPTICAL LENS
Document Type and Number:
WIPO Patent Application WO/2021/127857
Kind Code:
A1
Abstract:
A camera optical lens (10), sequentially comprising from an object side to an image side: a first lens (L1) having positive refractive power, a second lens (L2) having negative refractive power, a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6) having positive refractive power, and a seventh lens (L7) having negative refractive power. The first lens (L1) is made of glass. The second lens (L2) is made of plastic. The third lens (L3) is made of glass. The fourth lens (L4) is made of plastic. The fifth lens (L5) is made of plastic. The sixth lens (L6) is made of plastic. The seventh lens (L7) is made of plastic. The Abbe number of the first lens (L1) is v1. The Abbe number of the third lens (L3) is v3. The on-axis thickness of the seventh lens (L7) is d13. The axial distance between the image side surface of the sixth lens (L6) and the object side surface of the seventh lens (L7) is d12. The following relations are satisfied: 59.00≤v1≤82.00; 59.00≤v3≤82.00; d12/d13≥0.80. The camera optical lens (10) satisfies the design requirements of large aperture, wide angle, and ultra-thinness while having good optical properties.
