Abstract:
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.

Claim (Index 1):
An optical imaging lens, comprising a first element, a second element, a third element, a fourth element, a fifth lens element, a sixth lens element, a seventh lens element and an eighth lens element sequentially from an object side to an image side along an optical axis, each of the first, second, third, fourth, fifth, sixth, seventh and eighth lens elements having an object-side surface facing toward the object side and allowing imaging rays to pass through and an image-side surface facing toward the image side and allowing the imaging rays to pass through, wherein:\n the first lens element has positive refracting power; the second lens element has negative refracting power; a periphery region of the object-side surface of the third lens element is concave; both of the object-side surface and the image-side surface of the fourth lens element are aspherical surfaces; both of the object-side surface and the image-side surface of the fifth lens element are aspherical surfaces; an optical axis region of the object-side surface of the sixth lens element is convex, and an optical axis region of the image-side surface of the sixth lens element is convex; both of the object-side surface and the image-side surface of the seventh lens element are aspherical surfaces; an optical axis region of the image-side surface of the eighth lens element is concave; and the optical imaging lens comprises no other lenses having refracting power beyond the eight lens elements.
