Abstract
The disclosure discloses an optical imaging lens, which sequentially includes, from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens has positive refractive power, the fourth lens has positive refractive power, and the seventh lens has negative refractive power. A total effective focal length f of the optical imaging lens and a maximum Field Of View (FOV) of the optical imaging lens meet f×tan(FOV/2)?5.5 mm. An effective focal length f4 of the fourth lens and an effective focal length f6 of the sixth lens meet 1.3≤f4/f6<4.5.
