Title: HOLOGRAPHIC FILM OF PARTICULAR APPLICATION IN PHOTOVOLTAIC PANELS, IN SOLAR THERMAL PANELS AND IN SOLAR LIGHT DIFFUSION PANELS
Abstract:
The holographic film is made of transparent material such as polyester material and is characterized in that it implements at its interior one or more holographic lenses, each consisting of a myriad of holographic microlenses of infinitesimal size, of the order of a few microns, each microlens being adapted to converge the light rays of the same wavelength refracted thereby in a predetermined focus common to all microlenses.
