Abstract
An optical imaging lens from an object side to an image side includes a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. A optical-axis region of the object-side surface of the first lens element is convex, a periphery region of the image-side surface of the first lens element is convex, an periphery region of the object-side surface of the second lens element is convex, an periphery region of the object-side surface of the third lens element is convex, an optical-axis region of the image-side surface of the fourth lens element is convex, the fifth lens element has positive refracting power and the sixth lens element has positive refracting power. Only the above-mentioned six lens elements of the optical imaging lens have refracting power.
