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 T2 and an air gap G34 is between the third lens element and the fourth lens element along the optical axis to satisfy TTL/EFL≤1.000, TTL/G34≤12.000 and ALT/T2≤12.900.
