摘要
An energy dispersive X-ray analyzer is attached to a scanning electron microscope and includes: a SEM controller; a detector; an EDS controller; and a data processor. The data processor generates first and second X-ray mapping image respectively when the SEM controller controls the scanning electron microscope to irradiate the sample with an electron beam under first and second acceleration voltage conditions. The data processor corrects the first X-ray mapping image and the second X-ray mapping image into images that are independent of acceleration voltage condition based on a measurement intensity variation ratio of the X-ray when changed from the first acceleration voltage condition to the second acceleration voltage condition, and controls the display unit to display a difference image between the corrected first X-ray mapping image and the corrected second X-ray mapping image.
