<p>A process for producing an electromagnetic radiation filter includes at least two color filters, each formed from a stack on a stiff substrate of at least one dielectric layer and of metal layers in alternation, in order to transmit at least two colors. The process comprises depositing on said substrate a first metal layer, depositing on said first metal layer a first mechanically deformable dielectric layer having a set thickness e0, depositing on said first dielectric layer a second metal layer, imprinting the stack obtained with a mold applied to the entire surface of the stack and allowing material to be simultaneously moved in at least two zones of the stack, wherein in said at least two zones, two different thicknesses e1, e2 of said first dielectric layer are obtained, these two thicknesses being different from the set thickness e0 in the second depositing step, and removing the mold.</p> |
