Development of Soft X-ray Contact-type Microscope and Application to Micro-spectroscopy in Water-window

A contact-type microscope for the observation of organelles in a culture solution is fabricated with the use of a scintillator plate which shows high quantum efficiency and linearity in Water-window wavelength region. The fabricated microscope was applied to micro -spectroscopy, and an absorption spectrum of polystyrene beads was obtained from SX images taken by the microscope.
