Abstract Scope While high resolution microscopy is available at soft x-ray energies, some types of samples require better transmission in order to give sufficient signal. As phase contrast is significantly stronger than absorption contrast, it is in most cases beneficial to rely on the former. A hard x-ray Zernike phase contrast (ZPC) microscope based on refractive X-ray optics has been implemented with 17 keV photon energy, utilizing both monochromatic and pink beam radiation with 0.3% bandwidth. Significantly increased contrast has been achieved in a series of weakly absorbing samples, such as organic micron-sized colloid particles and Al-Si alloy microstructures. Contrast enhancement and the use of non-monochromatized radiation from undulator harmonics can reduce the exposure times required, and pave the way for ultra-fast microscopy imaging at high photon energies.
