“…Silver halide and dichromated gelatin need a chemical postprocessing to obtain the holographic gratings after the recording. 2,3 Self-processing holographic materials are those that offer the greatest versatility for use in different applications. Photopolymers, in particular, have a high resolution and the ability to be easily modified in a chemical laboratory.…”

In this work, reflection gratings has been stored in Bayfol X200 from Covestro. Up to two high-efficiency reflection holograms have been multiplexed in the same layer due to the physical thickness of the material films, 16 µm. The less material thickness, the fewer number of high diffraction efficiency multiplexed holograms we can store in it. Once multiplexed the pairs of holograms at different recording angles we have stuck several layers together, forming a multilayer system. From this multilayer system, we have obtained a wide diffracted spectrum were the result is the superposition of all the multiplexed gratings recorded in each layer. Therefore, this system has a good chromatic selectivity and allows us to select the reflected wavelengths and the spectral wide for each application.
