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, from an object side toward an image side in order along an optical axis comprising: a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element, said first lens element to said fifth lens element each having an object-side surface facing toward said object side to allow an imaging ray to pass through as well as an image-side surface facing toward said image side to allow said imaging ray to pass through, 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 object-side surface of said second lens element has a convex portion in a vicinity of a periphery of said second lens element; 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; 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, AAG is a sum of all four air gaps between each lens element from said first lens element to said fifth lens element and an air gap G 34  is between said third lens element and said fourth lens element along said optical axis to satisfy TTL/EFL\u22641.000 and 1.215\u2264AAG/G 34 \u22641.601.
