We have tried to accurately describe and generalize spatial distribution of the spread function for different cases of alignment of an X-ray polycapillary lens in angular and transverse coordinates. A series of experiments is carried out to determine the spread function of the lens in the areas corresponding to significant changes of the area of its focus in the longitudinal direction. An analysis of the results allowed us to propose two approximating models that can potentially approximate spread function with satisfactory accuracy for most typical cases of lens adjustment. A detailed analysis of the results of three series of experiments to determine the SF in a vast region of space with different cases of adjustment of a polycapillary lens made it possible to show that the models are universal and in good agreement with experimental SF distribution.
