The effect of UV radiation on the properties of diffraction gratings based on dichromated gelatin

详细

Results of experiments on the influence exerted by UV radiation on the height of the surface relief and on the diffraction efficiency of holographic diffraction gratings recorded on dichromated gelatin layers are reported. It is shown that the height of the surface relief substantially increases, which leads to a rise in the diffraction efficiency of the gratings to a value exceeding 25%.
