Using a near-field scanning microscope (NT-MDT) with a $100\mathrm{nm}$ aperture cantilever held $1\mathrm{\mu m}$ apart from a microaxicon of diameter $14\mathrm{\mu m}$ and period $800\mathrm{nm}$ , we measure a focal spot resulting from the illumination by a linearly polarized laser light of wavelength $\lambda =532\mathrm{nm}$ , with its FWHM being equal to $0.58\lambda$ , and the depth of focus being $5.6\lambda$ . The rms deviation of the focal spot intensity from the calculated value is 6%. The focus intensity is five times larger than the maximal illumination beam intensity.
