Abstract
An optical imaging lens includes: first, second, third, fourth, fifth and sixth lens element, an optical axis region of an image-side surface of the first lens element is concave, an optical axis region of an object-side surface of the second lens element is convex, an optical axis region of an object-side surface of the third lens element is convex, an periphery axis region of an object-side surface of the third lens element is concave, an optical axis region of an object-side surface of the fourth lens element is convex, an optical axis region of an object-side surface of the sixth lens element is concave. The lens elements having refracting power included by the optical imaging lens are only the six lens elements described above. In addition, the optical imaging lens satisfies the relationship: υ2+υ3≤60, and (G12+T2+T3+G34)/G23≤4.300.
