This article reviews on the fabrication advancement of X-ray reflect mirror fabrication in terms of technical requirements, fabrication and metrology development. Synchrotron radiation source, as a revolutionary light source, provides one of the most high-performance X-ray for scientific research, where reflect mirror plays an essential role in X-ray beam focusing. The short wavelength of X-ray demands reflecting photons only at a grazing angle of inci-dence on the extremely high-precision and smooth surface. Fabrication of such mirrors requires highly specialized equipment and technology that only a few foreign optic manufacturers possess, whereas manufacturers in China is laggard in this area. It is imperative to develop fabrication capability domestically as two synchrotron radiation facili-ties are under construction and several more projects are about to launch in the near future in China.
