http://openbooks.library.umass.edu/toggerson-132/chapter/matter-as-a-wave/ WebTransmission Electron Microscopes (TEM) use a broad electron beam to illuminate very thin, electron-transparent specimens, typically below 100 nm in thickness. To be able to pass through the samples, the electrons are typically accelerated to higher energies compared to those used in an SEM (using accelerating voltages of 60 – 300 kV).

WebHence, TEMs are often used to investigate molecular and cellular structures. How Does a TEM Work?
