The importance to have polarizers in the X-ray range is first justified. By comparaison to the other parts of the electromagnetic wavelength range, the different ways to get such polarizers is then briefly described . Artificial Bragg reflectors obtained by multilayers used like linear X-UV polarizers are finally considered and evaluated. An experimental device using two 45° reflections on multilayers, and analogous to crossed polarizers, is presented. For a demonstrative purpose, in the case of the 304A wavelength corresponding to the Hell line, first results of polarization rate measured by using Hf/Si multilayers is given.
