... with several wavelength-dispersive spectrometers and optimized for chemical analysis is usually called an electron microprobe. Energy-dispersive x-ray (EDX) microanalysis has the advantages of higher count rates and the simultaneous recording of the complete spectrum. Due to the higher count rates, EDX...

... of intensities. For example, electron diffraction in the transmission electron microscope (TEM) creates images in which the brightest spot can be millions of times stronger than the weakest spot. Representing this range with just 256 gray levels would lead to a large loss of information. Note that 16,384 levels...
