Abstract
An optical imaging lens includes a first lens element to a fifth lens element from an object side to an image side in order along an optical axis. The first lens element has positive refracting power and a periphery region of the image-side surface of the first lens element is concave, a periphery region of the object-side surface of the second lens element is convex, a periphery region of the object-side surface of the third lens element is convex, the fifth lens element has negative refracting power and optical axis region of the object-side surface of the fifth lens element is concave to satisfy (G12+G23+G34)/(G45+T5)≥2.500 and EFL*Fno/HFOV≥3.500 mm/degree.
