of the addition of dye to the honey was the one of increasing its diffraction efficiency, the experimental results
demonstrated that the gratings recorded in honey had bigger diffraction efficiency than those recorded in honey with dye.

Thus it was distinguished and analyzed the phenomenon behavior.

The existent techniques to produce high number of patterns replication, is determinates with the sampling theorem from Fourier theory. Following this line with matrix array of m x m points, we propose to construct a lens with hybrid optics technology; in our case we used a sum of Fourier holograms, to obtain four or more diffracted zones than the conventional conjugate pair of Fourier hologram. These codes are engravings in the surface of the glass lens. Using polymers or by techniques of glass erosion. To obtain a hybrid system lens with a hologram incorporate as one element. This point is important because reducing and agrees more value to conventional optics lenses; the lens can be adapted to production systems for mass patterns replication, for the graphic arts industry.
