Abstract: There is provided an imaging lens with excellent optical characteristics which satisfies demand of a low profile and a low F-number. An imaging lens comprises in order from an object side to an image side, a first lens with negative refractive power, a second lens with positive refractive power, a third lens with positive refractive power, a fourth lens with negative refractive power, a fifth lens with positive refractive power, a sixth lens, and a seventh lens with negative refractive power, wherein said fourth lens has an image-side surface being convex in a paraxial region, said seventh lens has an image-side surface being concave in a paraxial region, and predetermined conditional expressions are satisfied.

Abstract: 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.

Abstract: An imaging correction unit and an imaging module are provided. The imaging correction unit has an optical axis, and includes an optical turning element and two wedge-shaped optical elements. The optical turning element has a light emitting surface, and the light emitting surface has a first included angle with respect to the optical axis. Each of the two wedge-shaped optical elements has an inclined optical surface, and the inclined optical surface has a second included angle with respect to the optical axis. The light emitting surface of the optical turning element faces one of the two wedge-shaped optical elements, and the two wedge-shaped optical elements are rotatable relative to the optical axis.
