It’s not your ordinary microscope. It fires electrons at a sample. Which creates a high-resolution image by scanning the surface topography. As well as data about the surface composition.

Much like the traditional scanning electron microscope (SEM), the field emission scanning electron microscope uses electrons to illuminate a sample, instead of visible light as is used in optical ...

In electronics work, the scanning electron microscope (SEM) is the most common. You hit something with electrons and watch for secondary electron emissions. However, biologists more often use a ...

SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

Microscopy techniques based on electrons and X-ray photons have been ... correction and increasing computational speeds, electron microscopes can now image single atoms buried within structures ...
