We study the geometrical phase transition for fractal transmittances, to determine the limits from which it must be considered like fractal structure, according with the density of diffractive elements contained in such planar transmittance. For such objective two considerations are made: (1) the diffracted field from the transmittance is analyzed at the Fourier plane, (2) the autocorrelation of the same is studied by means of the joint transform correlator.
