Bright field Versus Dark-field TEM

Transmission electron microscopy (TEM) is a common technique for studying nanomolecular structures that cannot be resolved using traditional light microscopy. Compared with SEM (scanning electron microscopy) TEM provides images of cross-sections of a target subject and is suited to the study of objects such as organic tissue and crystalline lattices.
