Abstract
An optical imaging lens including a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element sequentially along an optical axis from an object-side to an image-side is provided. The optical imaging lens satisfies the condition expression of (G67+T7)/(T1+T2)≥1.600, wherein G67 is an air gap from the sixth lens element to the seventh lens element along the optical axis, T1 is a thickness of the first lens element along the optical axis, T2 is a thickness of the second lens element along the optical axis, and T7 is a thickness of the seventh lens element along the optical axis.
