Abstract:
An optical imaging lens includes a first lens of an image-side surface with a concave portion in a vicinity of its optical-axis, a second lens of an object-side surface with a convex portion in a vicinity of its optical-axis, a third lens of an image-side surface with a concave portion in a vicinity of its optical-axis, a fifth lens of negative refractive power and with a thickness along its optical-axis larger than that of the second lens. EFL is the effective focal length of the optical imaging lens, TTL is the distance from the object-side surface of the first lens element to an image plane, ALT is a total thickness of all five lenses, the second lens has a second lens thickness T 2  and an air gap G 34  is between the third lens element and the fourth lens element along the optical axis to satisfy TTL/EFL≤1.000, TTL/G 34 ≤12.000 and ALT/T 2 ≤12.900.

Claim (Index 1):
An optical imaging lens comprising first, second, third, fourth and fifth lens elements arranged from an object side to an image side in the given order along an optical axis of said imaging lens, each of said first, second, third, fourth and fifth lens elements having an object-side surface facing toward the object side and an image-side surface facing toward the image side, wherein:\n said image-side surface of said first lens element has a concave portion in a vicinity of the optical axis of said first lens element; said second lens element has negative refractive power; said object-side surface of said third lens element has a convex portion in a vicinity of the optical axis of said third lens element and said image-side surface of said third lens element has a concave portion in a vicinity of a periphery of said third lens element; said fifth lens element has negative refractive power and said image-side surface of said fifth lens element has a concave portion in a vicinity of the optical axis of said fifth lens element; the optical imaging lens comprises no other lenses having refracting power beyond the five lens elements; a sum of the Abbe number of said second lens element, the Abbe number of said third lens element and the Abbe number of said fourth lens element is greater than or equal to twice of the Abbe number of said first lens element; and EFL is an effective focal length of said optical imaging lens, TTL is a distance from said object-side surface of said first lens element to an image plane to satisfy TTL/EFL\u22641.000.
