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 along an optical axis from an object side to an image side, 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,
the first lens element is arranged to be a lens element in a first order from the object side to the image side and has a positive refracting power;
the second lens element is arranged to be a lens element in a second order from the object side to the image side;
the third lens element is arranged to be a lens element in a third order from the object side to the image side;
the fourth lens element is arranged to be a lens element in a fourth order from the object side to the image side;
the fifth lens element is arranged to be a lens element in a fifth order from the object side to the image side;
the sixth lens element is arranged to be a lens element in a sixth order from the object side to the image side; and
the optical imaging lens satisfies conditions of Gallmax/Fno≥3.600 millimeters, EFL/ImgH≥3.200, Gallmax/Tavg≥3.300, and a thickness of the fifth lens element along the optical axis is greater than an air gap along the optical axis between the fourth lens element and the fifth lens element, wherein Gallmax represents a largest air gap along the optical axis between the first lens element and an image plane, Fno represents an F-number of the optical imaging lens, EFL represents an effective focal length of the optical imaging lens, ImgH represents an image height of the optical imaging lens, and Tavg represents an average lens element thickness of all of the lens elements along the optical axis from the object side to the image plane,
wherein the optical imaging lens further satisfies conditions of (T4+G45+T5)/(T1+T6)≥2.100, wherein T1 represents a thickness of the first lens element along the optical axis, T4 represents a thickness of the fourth lens element along the optical axis, T5 represents the thickness of the fifth lens element along the optical axis, T6 represents a thickness of the sixth lens element along the optical axis, and G45 represents the air gap along the optical axis between the fourth lens element and the fifth lens element.
