A megohmmeter, or megger as it is more commonly known, is an electrical test instrument designed to test extremely high resistances by producing a DC (direct current) voltage of between 300 and 15,000 volts.
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen as it passes through. TEM is composed of several components, which include a vacuum system in which the electrons travel, an electron emission source for generation of the electron stream, a series of electromagnetic lenses, as well as electrostatic plates. The latter two allow the operator to guide and manipulate the beam as required.
