Using an iterative method modernized with the adaptive subadjustment, we calculated phase functions of the focusators into a longitudinal axial line-segment, which is characterized by the constant light intensity along the line. Numerical studies were performed of a focal area: a character of variations of both the transverse diameter and the focusing efficiency along a line are reported.
