Optical imaging lens assembly including six lenses of +−+−+− refractive powers

Abstract

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.

Dependencies are inferred from the claim text.
