WebSEMs usually use acceleration voltages up to 30 kV, while TEM users can set it in the range of 60–300 kV. The magnifications that TEMs offer are also much higher compared to SEMs. TEM users can magnify their samples by more than 50 million times, while for the SEM, this is limited to 1–2 million times. WebAtom Electron Microscope. An atom electron microscope is an advanced electron microscope that achieves exceedingly high resolution using electron beams, as opposed to light, to illuminate the specimen (atoms). This work is referred to as atom microscopy. This task is no easy feat, as atoms are an element’s tiniest unit.
