Abstract

An optical imaging lens includes a first lens element to a sixth lens element. An optical axis region of the object-side surface of the first lens element is convex, an optical axis region of the image-side surface of the second lens element is convex, an optical axis region of the object-side surface of the third lens element is convex, the fourth lens element has negative refracting power, an optical axis region of the object-side surface of the fourth lens element is concave, a periphery region of the object-side surface of the fifth lens element is concave, an optical axis region of the object-side surface of the sixth lens element is convex and an optical axis region of the image-side surface of the sixth lens element is concave to satisfy (G12+T3+G34+T4+G45+T5)/EFL≥1.200.
