Abstract
The present invention relates to the field of optical lenses, and provides an imaging optical lens and a lens assembly. The imaging optical lens is composed of an aperture and seven lenses, which are, in order from the object side to the image side, a first lens having positive refractive power, a second lens having negative refractive power, a third lens having negative refractive power, a fourth lens having positive refractive power, a fifth lens having negative refractive power, a sixth lens having positive refractive power, and a seventh lens having negative refractive power, and satisfy the following conditional expressions: -8.00≦(SAG51 / SD51*R9) / (SAG72 / SD72*R14)≦-3.30, 0.80≦HC71 / SD71≦0.95, 0.85≦HC72 / SD72≦0.97, 1.10≦(d10+d12) / d11≦2.10.
