Patent ID: 10444468

Abstract:
An optical imaging lens includes: first, second, third, fourth, fifth, sixth and seventh lens element, an image-side surface of the first lens element has a concave optical axis region, an object-side surface of the third lens element has a concave periphery region, the fourth lens element has positive refractive power, an object-side surface of the fourth lens element has a concave optical axis region, an image-side surface of the sixth lens element has a concave optical axis region. The lens elements having refracting power included by the optical imaging lens are only the seven lens elements described above. In addition, υ3, υ4, υ5, υ6 and υ7 are the Abbe numbers of the third, fourth, fifth, sixth and seventh lens element respectively, and satisfying the relationship: υ3+υ4+υ5+υ6+υ7≥220.000.
