Abstract
A method for producing a contrast-amplifying support comprising an absorbing substrate carrying at least one absorbing layer comprises a design step for the support and the following steps: i) choosing an illumination wavelength λ; ii) choosing a material constituting the substrate and exhibiting, at illumination wavelength λ, a complex refractive index N0=n0−jk0 with k0≥0.01; iii) choosing an ambient medium in contact with the layer on the side opposite to the substrate and exhibiting, at illumination wavelength λ, a complex refractive index N3=n3−jk3 with k3≥0; iv) determining a nominal complex refractive index N1=n1−jk1 and a nominal thickness e1 of the layer wherein it behaves in the guize of antireflection layer when illuminated under normal incidence at illumination wavelength λ; and v) choosing a material constituting the layer and exhibiting, at illumination wavelength λ, a complex refractive index whose real and imaginary parts coincide with the nominal complex refractive index.
