    Sammanfattning : Hard x-ray nanoimaging enables structural investigations of new materials for many applications. For high-resolution experiments, zone plate x-ray optics are commonly chosen.Two methods of zone plate nanofabrication are presented in this thesis.Zone plates are circular diffraction gratings with radially decreasing grating period.
