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 EFL/(G12+G67)≤5.600, wherein EFL is an effective focal length of the optical imaging lens, G12 is an air gap from the first lens element to the second lens element along the optical axis, and G67 is an air gap from the sixth lens element to the seventh lens element along the optical axis.
