1. an optical imaging system, is characterized in that, is extremely comprised successively as side by thing side:

  • First lens, has refractive power;

    The second lens, have refractive power;

    The 3rd lens, have refractive power;

    The 4th lens, have refractive power;

    The 5th lens, have refractive power;

    The 6th lens, have refractive power;

    AndImaging surface, the lens that wherein said optical imaging system has refractive power are six pieces, described first saturatingMirror at least one lens in described the 6th lens have positive refractive power, and the thing side of described the 6th lensSurface and be aspheric surface as side surface, described first lens to the focal length of described the 6th lens is respectivelyF1, f2, f3, f4, f5, f6, the focal length of described optical imaging system is f, described optical imaging systemEntrance pupil diameter be HEP, described first lens thing side has distance H OS to described imaging surface,Described first lens thing side to described the 6th lens have apart from InTL as side on optical axis, multipleIn described lens, the intersection point of the thing side surface of each lens on optical axis is to each in multiple described lensThe maximum effective diameter position of the thing side surface of mirror in the absolute value summation of the horizontal displacement distance of optical axis isInRSO, the intersection point of the picture side surface of multiple described lens on optical axis is to the picture side table of multiple described lensThe maximum effective diameter position of face is InRSI in the absolute value summation of the horizontal displacement distance of optical axis, InRSOAnd the summation of InRSI is Σ
