Patent ID: 8530858

Claim:
A transmission electron microscope apparatus comprising: an electron gun for emitting an electron beam; a condenser lens for converging the emitted electron beam; a plurality of sample stages irradiated with the converged electron beam and adapted to mount a plurality of samples; a sample movement control unit for moving said plurality of sample stages; image-forming lenses for forming an image of an electron beam having transmitted through said plurality of samples; an electron spectrometer adapted to perform spectrometry of the electron beam in accordance with energy amounts that the image-formed electron beam has and deliver spectral images obtained at convergence positions which are different in an energy dispersion axis direction and in a direction orthogonal to the energy dispersion axis direction to thereby acquire spectral images from the plurality of samples at a time; and an image display unit for displaying acquired spectral images, wherein: the plurality of samples mounted on said plurality of sample stages, respectively, are arranged in a direction orthogonal to the energy dispersion axis direction of said electron spectrometer, said plurality of sample stages on which the plurality of samples are mounted are arranged such that the converged electron beam is simultaneously irradiated onto samples mounted on more than two sample stages, and the plurality of samples are mounted such that electron beams transmitted through the plurality of samples are disposed in different positions in the direction orthogonal to the energy dispersion axis direction of said electron spectrometer.
