Abstract:
An object of the present invention relates to high-resolution observation on a light field STEM, a dark field image STEM, and an EELS, at a low acceleration voltage. The present invention relates to controlling on incorporation angles of a STEM detector and an electron energy loss spectroscopy by changing the disposition of a sample with respect to an optical axis direction of a primary electron beam in a scanning transmission microscopy including an electron energy loss spectroscopy. According to the present invention, it is possible to easily control an optimum scattering angle in each of a light field STEM, a dark field STEM, and an EELS while suppressing occurrence of chromatic aberration accompanying the controlling on the incorporation angle.

Claim (Index 1):
A scanning transmission microscopy comprising:\n an electron source that emits a primary electron beam; a stage drive mechanism that moves a sample table holding a sample; an objective magnetic field lens that focuses the primary electron beam on the sample; a scanning coil that two-dimensionally scans the primary electron beam irradiated on the sample; a STEM detector that detects the electron transmitted the sample; and an electron energy loss spectroscopy that detects energy loss spectrum of electrons transmitted the sample, wherein incorporation angles of the STEM detector and the electron energy loss spectroscopy by changing disposition of the sample with respect to an optical axis direction of the primary electron beam are controlled.
