TRANSMISSION ELECTRON MICROSCOPE HAVING ELECTRON SPECTROSCOPE

摘要

A transmission electron microscope is capable of correcting, with high efficiency and high accuracy, an electron energy loss spectrum extracted from each of measured portions included in an electron energy loss spectral image with two axes representing the amount of an energy loss and positional information on a measured portion. The transmission electron microscope has an electron spectroscope and a spectrum correction system. The spectrum correction system corrects a spectrum extracted from each measured portion included in an electron energy loss spectral image acquired from a sample based on a difference between a spectrum extracted from a standard portion of a standard spectral image and a spectrum extracted from a portion different from the standard portion.
