An optical imaging lens includes first, second, third, fourth, fifth, and sixth lens elements sequentially along an optical axis from an object side to an image side. Each of the first to the sixth lens elements includes 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 optical imaging lens satisfies conditions of Gallmax/Fno≥3.600 millimeters, EFL/ImgH≥3.200, and Gallmax/Tavg≥3.300; here, Gallmax represents a largest air gap along the optical axis between the first lens element and an image plane, Fno, EFL, and ImgH respectively represent an F-number, an effective focal length, and 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.

Optical imaging lens

In an optical imaging lens, a first lens element has negative refracting power, a second lens element has negative refracting power, an optical axis region of the object-side surface of the third lens element is concave, an optical axis region of the object-side surface of the fourth lens element is convex, an optical axis region of the object-side surface of the fifth lens element is convex, a sixth lens element is arranged to be a lens element in a second order from an image-side to an object-side and a seventh lens element is arranged to be a lens element in a first order from the image-side to the object-side to satisfy: (G23+T3+T4+G45)/L57&#x2265;2.700 and1+2&#x2264;80.000.
