In order to realize diffraction-limited focusing of hard X-rays with a size less than several hundreds of nanometers, a deformable mirror which can be bent into an aspherical shape with a depth of several micrometers and an accuracy better than a few nanometers was developed. The accuracy of the mirror surface shape was guaranteed and maintained by a feedback system with a Fizeau interferometer. Hard X-ray focusing performance of the mirror was tested at the BL29XUL of SPring-8. We confirmed that beam size was controllable in a range from micrometer to nanometer scale under diffraction-limited focusing condition.
