Transmission Electron Microscopy (TEM) is a standard laboratory technique. TEM is indispensable tool for high resolution observation of very fine structures on material smface. The resolution of TEM is abou one order of magnitude better than that of SEM. It corresponds to 1 nm. There exist also high resolution transmission microscopes (HRTEM) with a resolution down to 0.1 nm, capable to resolve individual atomic lattice planes. Samples must be stable enough to withstand the electron beam impact during their examination. This can be a problem for polymers.
