Electron microscopy (EM) allows us to observe a world exponentially smaller than the one we can see with our unaided eyes or even with the familiar light microscope. Electron microscopy uses electrons to “see” small objects in the same way that light beams let us observe our surroundings or...

SEM vs TEM - SEM vs TEM advantages - SEM vs TEM similarities and differences Every electron microscope works by accelerating a focused stream of electrons in a vacuum towards a sample. Interactions between the electron beam and the sample create an image, similar to how optical microscopes use ...

The two main types of electron microscopes are the transmission electron microscope (TEM) and the scanning electron microscope (SEM). Here, we briefly describe their similarities and differences. The difference between SEM and TEM The main difference between SEM and TEM is that SEM creates ...
