PROBLEM TO BE SOLVED: To attain observation of an image projected on a fluorescent plate without distortion in a transmission electron microscope.SOLUTION: An electron microscope includes: an electron gun which generates an electron beam; a lens barrel which maintains a passage part of the electron beam vacuum; an irradiation part which irradiates the electron beam on a sample; an image formation part which magnifies the electron beam transmitted the sample; a fluorescent plate on which a magnified sample image is projected; a mirror which reflects the image on the fluorescent plate; and an external camera which picks up an image on the mirror, in which the mirror is arranged inside the lens barrel, and out of the passage area of the electron beam. |
