General Purpose Electron Sources
These universal use electron sources provide a wide range of beam currents and spot sizes, including but not limited to those shown below. Typical applications include AUGER (AES), Energy Loss Spectroscopy (ELS), X-ray analyses (XPS) and cathodoluminescence studies.
High current versions (-HC) are available.
