Ultraprecise imaging optics, which consists of two sets of elliptical mirrors and hyperbolic mirrors aligned perpendicular to each other (i.e., advanced Kirkpatrick-Baez mirrrors), is developed to realize high-resolution and achromatic full-field hard-X-ray microscopy. Experiments to form a demagnified image (with horizontal and vertical demagnification factors of 385 and 210, respectively) are conducted to evaluate the optical system at an X-ray energy of 11.5 keV at SPring-8. Results show that the imaging system can form a demagnified image with nearly diffraction-limited resolutions of ~50 nm in the horizontal and vertical directions. The field of view is also experimentally estimated to be ~12 × ~14 μm(2) when used as a magnification imaging system.
