The Electron Microscopy shared resource offers techniques that allow researchers to resolve structures from cellular ultrastructure all the way down to molecular interactions. Our expertise in EM ...

The beam is focused onto the sample using metal apertures and magnetic lenses. There are two different types of electron microscopy, scanning electron microscopy (SEM) and transmission electron ...

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 ...

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 ...
