Abstract

An optical imaging lens includes a first lens element to a sixth lens element. An optical axis region of the image-side surface of a first lens element is convex, a periphery region of the image-side surface of the second lens element is concave, an optical axis region of the image-side surface of the third lens element is convex, a periphery region of the image-side surface of the third lens element is convex, the fourth lens element has positive refracting power and a periphery region of the object-side surface of the fourth lens element is concave, an optical axis region of the object-side surface of the fifth lens element is convex, an optical axis region of the object-side surface of the sixth lens element is convex and a periphery region of the object-side surface of the sixth lens element is concave to satisfy Fno*AAG/(T3+G34)≤3.000.
