The Thermo Fisher Apreo 2 Variable Pressure Field Emission Scanning Electron Microscope (FE-SEM) is a thermionic field emission high-resolution scanning electron microscope. The Apreo 2 FE-SEM is an ...

Since the FE-SEM is in effect an electrical circuit, the specimen must be conductive. In the tungsten source SEM, any nonconductive specimen is coated with a very thin layer of conductive material in ...
