An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly, an aperture, and a second lens assembly. The first lens assembly includes a first lens having negative refractive power and a second lens having positive refractive power. The second lens assembly includes a third lens having positive refractive power, a fourth lens having negative refractive power, and a fifth lens having positive refractive power. The optical imaging lens satisfies: −5<fg1/F<−3.5 and 1.5<fg2/F<2.5; F is a focal length of the optical imaging lens; fg1 is a focal length of the first lens assembly; fg2 is a focal length of the second lens assembly, thereby achieving the effect of high image quality.

Optical imaging lens

An optical imaging lens, in order from an object side to an image side along an optical axis, includes a first lens assembly, an aperture, and a second lens assembly. The first lens assembly has negative refractive power and includes a first lens, a second lens, and a third lens. The first lens has negative refractive power. The second lens has negative refractive power. The third lens has positive refractive power. The second lens assembly has positive refractive power and includes a fourth lens, a fifth lens, and a sixth lens. The fourth lens has positive refractive power. The fifth lens has negative refractive power. The sixth lens has positive refractive power. In this way, the optical imaging lens of the present invention not only could achieve the effect of high image quality and low distortion, but also could reduce the volume of the optical imaging lens.
