Transmission electron microscopes

In Transmission Electron Microscopy (TEM) a thin sample is exposed to a focused beam of electrons. The beam is modified as it passes through the sample to produce an image. This image can then be magnified with lenses and focused onto a scintillator attached to a CCD or other sensor or surface such as a fluorescent screen or photographic film. There are many different transmission electron microscopes and instruments (more) in which it is combined with other techniques to create high-resolution images.
