摘要： 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.

摘要： An optical imaging lens includes a first lens element, a second lens, a third lens element and a fourth lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. The first lens element has positive refracting power, an optical axis region of the object-side surface of the second lens element is convex, a periphery region of the image-side surface of the second lens element is convex, and the fourth lens element has negative refracting power, and an optical axis region of the object-side surface of the fourth lens element is convex. The lens elements included by the optical imaging lens are only the four lens elements described above. The optical imaging lens satisfies the following conditions: υ1+υ4≤100.000 and TTL/T1≤5.500.

摘要： The present disclosure provides for various embodiments of optical imaging lenses. An optical imaging lens may comprise at least eight lens elements positioned in an order from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least an inequality, the optical imaging lens may exhibit improved optical characteristics, the total length of the optical imaging lens may be shortened, and the view angle and f-number may also be improved.
