Kinoform optics applied to X-ray photon correlation spectroscopy
Journal of Synchrotron Radiation, 2010 Moderate-demagnification higher-order silicon kinoform focusing lenses have been fabricated to facilitate small-angle X-ray photon correlation spectroscopy (XPCS) experiments. The geometric properties of such lenses, their focusing performance and their applicability for XPCS measurements are described.
