摘要：
We fabricated a spiral field-intensity distribution in a near-field when a laser beam was focused by a binary phase spiral axicon. It is shown by means of 3D-simlation in Comsol and life experiments with the near-field microscope NT-MDT Integra Spectra. Derived experimental measurements have been verified by the numerical simulations.
