HOLOGRAPHIC FILM OF PARTICULAR APPLICATION IN PHOTOVOLTAIC PANELS, IN SOLAR THERMAL PANELS AND IN SOLAR LIGHT DIFFUSION PANELS

摘要

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.
