本文总结了当前同步辐射 X射线反射镜光学制造技术的需求背景、发展现状以及未来方向。同步辐射光源是国家重大科学装置, 作为同步辐射光源重要光学元件的 X射线反射镜, 直接决定着光学调制品质。短波长掠入射的特殊应用场景, 使 X射线反射镜有着更为特殊且高精度的面形要求, 其加工与检测技术长期为国外所垄断, 国内发展较为缓慢, 面对国内未来同步辐射装置的建设需求, 我国亟需打破这一现状。

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.
