Abstract
The disclosure discloses an optical imaging lens. The optical imaging lens sequentially from an object side to an image side along an optical axis includes, a first lens with refractive power, a second lens with positive refractive power, a third lens with negative refractive power, a fourth lens with refractive power, a fifth lens with refractive power, a sixth lens with refractive power, a seventh lens with positive refractive power and an eighth lens with negative refractive power. A total effective focal length f of the optical imaging lens and the maximum Field of View (FOV) of the optical imaging lens meet f×TAN(FOV/2)>4.0 mm; and the total effective focal length f of the optical imaging lens, a center thickness CTof the seventh lens on the optical axis and a CTof the eighth lens on the optical axis meet f/(CT+CT)≥5.0.
