WebTEM systems operate by focussing a broad electron beam onto an ultra-thin sample and measuring the transmission of electrons using a fluorescent detection screen placed below it. As the beam completely penetrates the specimen, the 2D image generated can offer invaluable insights into internal structures with unprecedented accuracy. WebThere are two main types of electron microscope – the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a …
