Abstract

An optical imaging lens includes, sequentially from an object side to an image side along an optical axis, a first to seventh lens elements each having an object-side surface and an image-side surface. The optical imaging lens satisfies a conditional expression: (G56+T6+G67)/(TG34+GT45)≥2.600. G56 is an air gap from the fifth to the sixth lens element along the optical axis. T6 is a thickness of the sixth lens element along the optical axis. G67 is an air gap from the sixth to the seventh lens element along the optical axis. TG34 is a distance from the object-side surface of the third lens element to the object-side surface of the fourth lens element along the optical axis. GT45 is a distance from the image-side surface of the fourth lens element to the image-side surface of the fifth lens element along the optical axis.
