To realize a variable beam size optical system for multiple X-ray analyses, we have developed a new monolithic bimorph mirror based on a single-crystal piezoelectric element that has a simple structure but can have large deformation. The proof-of-concept test performed at SPring-8 showed that the beam size can be changed between 1 mm and sub 1 µm at an X-ray energy of 10 keV.
