S. Bac et al., USE OF A LAMELLAR MULTILAYER AMPLITUDE GRATING AS A NARROW BANDPASS MONOCHROMATOR AND ENERGY SEPARATOR, Optics communications, 144(4-6), 1997, pp. 281-291
An experimental study of the diffraction of X rays in the keV region b
y a lamellar multilayer amplitude grating is described. This optics is
obtained by periodic etching of an interferential multilayer mirror d
own to the substrate. The advantages provided by the etching to the sy
stem response and its use as an energy separator are given. (C) 1997 P
