Abstract
The X-ray lens is a key technology for the X-ray microscopy at synchrotron radiation (SR) facility. Various types of the focusing optics (lens) for high-energy X-rays have been developed up to now. A multilayer Fresnel zone plate (FZP), which consists of periodic multilayer structure, is one of promising optics. In this review paper, firstly the recent status of various focusing optics for high-energy SR X-rays is described. And next, some of our representative results of the multilayer FZP with high diffraction efficiency and the X-ray microscopic image are shown.
