The present status of X-ray optics in high-energy domain, an area in which much progress has been made in recent years, is reviewed with respect to lateral resolution, flux, imaging capability. The latest results on development of new focusing devices such as compound refractive lenses are shown. Hard X-ray microscopy techniques realized at the ESRF undulator beamline ID22 are presented. Some recent application in imaging,
spectroscopy and microdiffraction are briefly described.
