    摘要: Device of the mirror type in the range of X-UV rays, comprises a periodic stack, on a support, of a system of superimposed layers, which system includes a lower layer of a first heavy element reflecting at the wavelengths of application of the mirror, and an upper spacer layer of a light element which has low optical absorption at these wavelengths. The system of superimposed layers comprises, between the lower layer and the upper layer, an intermediate layer of a second heavy element reflecting at the wavelengths of application to form a three-layer system. The heavy elements are selected to form together with the spacer element first and second pairs, first of which has greater absorption at the wavelengths of application and exhibits a ratio of contrast of real and complex indices lower than the other second pair. The heavy element of the first pair forms the lower layer of the three-layer system, the intermediate layer being composed of the heavy element of the second pair.
