Abstract
X-ray microscopy enables high-resolution analysis of thick specimens such as several microns in aqueous and atmospheric pressure environments in fields of biological and material sciences. Most commonly, zone plates (ZPs) are used as optical elements in combination with the use of synchrotron radiation (SR) as an x-ray source. It is realized at the x-ray microscopy station at BL-12 of Ritsumeikan SR center. The highest spatial resolution is 45 nm. This X ray microscope has been applied in biology, medicine, and material science. Various specimens can be clearly observed. We report some applied researches of our X-ray microscope.
