WebHowever, while the SEM uses a focused beam of electrons to image the sample in the chamber, a FIB setup uses a focused beam of ions instead. Unlike an electron microscope, FIB is inherently destructive to the specimen. When the high-energy gallium ions strike the sample, they will sputter atoms from the surface. WebSEM and TEM differ in the manner in which users operate their systems. SEMs usually use up to 30 kV of acceleration voltages, while TEM users can configure it between 60 and 300 kV. TEM magnifications are also much higher than the capacity of SEMs. TEM users can magnify their samples more than 50 million times, while SEM users can only magnify ...
