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 having positive refractive power; a second lens having refractive power; a third lens having refractive power; a fourth lens having negative refractive power, wherein an object-side surface thereof is a concave surface, while an image-side surface is a convex surface; a fifth lens having positive refractive power; and a sixth lens having negative refractive power, wherein an object-side surface thereof is a convex surface. TTL is a distance from an object-side surface of the first lens to an imaging surface of the optical imaging lens on the optical axis, ImgH is a half of a diagonal length of an effective pixel region on the imaging surface of the optical imaging lens, TTL and ImgH meet 4.0 mm<ImgH/(TTL/ImgH)<7.0 mm. Therefore, the optical imaging lens has high imaging quality.

Optical imaging lens including six lenses of +-+-+-or +++-+-refractive powers

The disclosure provides an optical imaging lens assembly, which sequentially includes, from an object side to an image side along an optical axis, a first lens with a positive refractive power, a second lens, a third lens with a positive refractive power, a fourth lens, a fifth lens with a positive refractive power and a sixth lens with a negative refractive power, wherein a total effective focal length f of the optical imaging lens assembly and an entrance pupil diameter (EPD) of the optical imaging lens assembly meet f/EPD<1.35; and an effective focal length f3 of the third lens, an effective focal length f5 of the fifth lens and an effective focal length f1 of the first lens meet 0.9<(f3+f5)/f1<1.7.
