Spectrum display device for x-ray microanalyzer or the like

摘要

A display for an x-ray microanalyzer including a wavelength- dispersive x-ray spectrometer and an energy-dispersive x-ray spectrometer for producing two kinds of spectra from the same region on a specimen. A circuit enables markers to be superimposed on the spectra to indicates some wavelengths and energies of the characteristic x-ray emanating from a chemical element selected by the operator. The markers faciliatate precisely confirming the existence of the element in the region, based on the two kinds of spectra.
