The purpose of this paper is to develop the calculation method of diffractive lenses with the given transmittance that
allows determining structural parameters of diffractive lenses. To this end, we employ the example of one of the
options of lenses transmittance. We show that the lens with the same parameter works as a Fresnel zone plate. In
addition, we analyze the intensity distribution generated by this plate was analyzed. We show that with the increase of
a focus number the focus intensity decreases, while the highest intensity is observed for the main focus. The focuses
position depends on the wavelength, bandwidth and the focus number, whilst the intensity depends on a number of
bands and the focus position. The bandwidth is determined by the modulation of diffraction lenses and wavelength.
