Claim 0:
1. An optical imaging lens, comprising a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element sequentially arranged from an object side to an image side along an optical axis, wherein each of the first lens element to the sixth lens element comprises an object-side surface facing the object side and allowing imaging rays to pass through and an image-side surface facing the image side and allowing the imaging rays to pass through, wherein
the first lens element has a positive refracting power, and an optical axis region of the image-side surface of the first lens element is convex and has a negative radius;
the second lens element has a negative refracting power;
the third lens element has a positive refracting power;
the fourth lens element has a negative refracting power;
the fifth lens element has a positive refracting power;
an optical axis region of the image-side surface of the fifth lens element is concave; and
lens elements of the optical imaging lens only comprise the first lens element to the sixth lens element and satisfy the following conditional expressions: (T3+G34)/T4≥1.900 and (HFOV×ImgH)/EFL≥50.000°, where T3 is a thickness of the third lens element along the optical axis, T4 is a thickness of the fourth lens element along the optical axis, G34 is an air gap from the third lens element to the fourth lens element along the optical axis, HFOV is a half field of view of the optical imaging lens, ImgH is an image height of the optical imaging lens, and EFL is an effective focal length of the optical imaging lens.
