A contact-type microscope was successfully developed and SX images can be instantly obtained without any SX imaging optics by the microscope. In the microscope, a SX image is converted to a visible (VI) image with the use of the scintillator plate, and the VI image is read out by a VI optical microscope installed in the microscope. The microscope can be adaptable to any SX light sources, such as syncrotron light source and laser produced plasma (LPP) light source. In the study, a "living" bio-cell was observed by a contact-type SX microscope using LPP light source, and the obtained images were compared with VI luminessence images taken at the same position. Origins of the structures contained in the SX images are clarified by the comparison between the two. Spectromicroscopic images by the use of a syncrotron light source were also obtained for investigating high contrast SX images in Water-window wavelength region.
