In a transmission electron microscopy (TEM), a thin electron beam transparent specimen (ideally ≤ 100 nm) is exposed to a high-energy (typically 60 - 300 keV) electron beam.

The transmission electron microscope (TEM) operates on many of the same optical principles as the light microscope. The TEM has the added advantage of greater resolution.
