The X-ray signal in electron microscopes is usually collected by compact solid state detectors based on lithium-drifted silicon diodes. The X-ray photon is sorted by energy, hence the alternative names for X-ray fluorescence analysis are Energy Dispersive X-ray Spectroscopy (EDS or EDX).

The solid-state EDS detectors are attached to the columns of the electron microscopes and normally consist of a collimator, window, lithium-drifted silicon detector, field effect transistor (FET), Dewar, and preamp as shown in Figure 4656.
