Abstract: A vacuum sample chamber for a particle and optical device includes on one surface thereof, an aperture through which a particle beam to be focused along an optical axis of particles such as electrons, ions and neutral particles is incident; and on the opposite surface thereof, a detachable sample holder through which light penetrates, thereby enabling a sample to be observed and analyzed by means of the particle beam and light. A sample chamber is capable of reducing observation time by maintaining a vacuum therein even when a sample is put into or taken out from a sample chamber of an electron microscope or focused ion beam observation equipment, and capable of obtaining an optical image on the outside thereof without inserting a light source or an optical barrel into the sample chamber. A light-electron fusion microscope comprising the sample chamber.
