CONTRAST AMPLIFYING SUPPORT FOR THE OBSERVATION OF A SAMPLE, PRODUCTION METHODS THEREOF AND USES THEREOF

A contrast-amplifying support for the observation of a sample, comprises a transparent substrate carrying at least one absorbing layer whose complex refractive index N1=n1−jk1 and thickness are chosen in such a way that the layer behaves in the guise of antireflection layer when it is illuminated un...

Zusammenfassung:A contrast-amplifying support for the observation of a sample, comprises a transparent substrate carrying at least one absorbing layer whose complex refractive index N1=n1−jk1 and thickness are chosen in such a way that the layer behaves in the guise of antireflection layer when it is illuminated under normal incidence at an illumination wavelength λ through the substrate, the face of the layer opposite to the d substrate being in contact with a transparent so-called ambient medium whose refractive index n3 is less than that of the refractive index n0 of the substrate. Methods for producing a contrast-amplifying support and for observing a sample, or for detecting or assaying at least one chemical or biological species, using such a contrast-amplifying support are provided.
