摘要： The present invention provides an optical imaging lens. The optical imaging lens comprises eight lens elements positioned in an order from an object side to an image side. Through controlling convex or concave shape of surfaces of the lens elements, the optical imaging lens may shorten system length with a good imaging quality.

摘要： An optical imaging lens includes a first lens element to a sixth lens element from an object side to an image side along an optical axis. An optical axis region of the object-side surface of the first lens element is concave, a periphery region of the object-side surface of the second lens element is convex, a periphery region of the image-side surface of the fourth lens element is concave, an optical axis region of the object-side surface of the fifth lens element is convex and a periphery region of the image-side surface of the sixth lens element is convex. Lens elements included by the optical imaging lens are only six lens elements described above. ImgH is an image height of the optical imaging lens and AAG is a sum of five air gaps from the first lens element to the sixth lens element along the optical axis to satisfy ImgH/AAG≥3.200.

摘要： An optical imaging lens may include a first, a second, a third, a fourth, a fifth, a sixth and a seventh lens element positioned in an order from an object side to an image side along an optical axis. Through designing concave and/or convex surface of the lens elements, the optical imaging lens may have improved imaging quality and improved assembly yield while the optical imaging lens may satisfy (|Sag51/ER51|+|Sag52/ER52|)/2≤20.000%, wherein a Sag of an optical boundary of the object-side surface of the fifth lens element is represented by Sag51, a Sag of an optical boundary of the image-side surface of the fifth lens element is represented by Sag52, an effective radius of the object-side surface of the fifth lens element is represented by ER51, and an effective radius of the image-side surface of the fifth lens element is represented by ER52.

摘要： An optical imaging lens includes a first lens element, a second lens, an aperture stop, 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. An optical axis of the image-side surface of the first lens element is convex and an optical axis of the image-side surface of the fourth lens element is concave. HFOV stands for the half field of view of the entire optical imaging lens and TTL is a distance from the object-side surface of the first lens element to an image plane along the optical axis to satisfy HFOV/TTL≤1.500°/mm.

摘要： An optical imaging lens may include a first, a second, a third, a fourth, a fifth, and a sixth lens elements positioned in an order from an object side to an image side. Through designing concave and/or convex surfaces of the six lens elements, the improved optical imaging lens may provide better imaging quality while the length of the lens may be shortened, the F-number may be reduced, and the field of view may be extended.
