A sample dispersing device contains a container inside of which a dispersal chamber where a power sample is dispersed is formed, and an introducing mechanism that introduces a gas containing the powder sample from the outside of the container into the dispersal chamber based on a pressure difference between the inside and the outside of the container. The introducing mechanism contains an introduction pipe where the gas containing the powder sample flows, and several restrictors arranged in the introduction pipe.

Sample dispersing device

A scintillatoris disposed on an incidence sideof a photomultiplier. A scintillator capfor introducing electrons into the scintillatoris disposed around the scintillator. The photomultiplieris disposed in a sample chamberwith a vacuum seal formed around the photomultiplier. An insulating membermade of an opaque material is disposed between the scintillator capand the photomultiplier. The insulating memberprovides insulation between the scintillator capand the photomultiplier. The lateral circumference of the photomultiplieris covered to prevent light from entering the photomultiplier. A band filterfor blocking the illumination light of an optical microscopeis disposed between the scintillatorand the incidence sideof the photomultiplierto make it possible to conduct simultaneous observations by using the electrons and the optical microscope.
