Transmission electron microscopy (TEM) is a technique used to observe the features of very small specimens. The technology uses an accelerated beam of electrons, which passes through a very thin specimen to enable a scientist the observe features such as structure and morphology.
Transmission electron microscopy is a major analytical method in the physical, chemical and biological sciences. TEMs find application in cancer research, virology, and materials science as well as pollution, nanotechnology and semiconductor research, but also in other fields
