Transmission electron microscope (TEM) electron microscope is used, for example, some types of studies which prepared by electron beam particle method to pass through. Create image from a camera of this type is done by measuring the electron passes through the samples themselves. The machine is suitable for TEM study on the details of the internal elements of, for example, an element within a cell membrane, cell wall, cell's style that will give you the details above other types of microscope because an expanding and powerful distribution detail (maximum estimate is 0.1 NM). The principle consists of the origin of the electron-electron to enter acting production systems. Therefore, the electrons from the cradle will be accelerated by electric. Then a group of electrons to pass through the lens (condenser lens) radiation is collected in order to make the Group an electron becomes an electron beam. Which can be adapted to the size of a beam of electrons is larger or smaller as needed. Then the electron beam moving through, for example, to study the sample (specimen) to study must look at the flat and very thin (often found in the range of between 1-100 nm) and then an electron passes through a krachoeng particle when, for example, and electronic check.The Plains through this example, it will be the focus of the lens near the image object (objectivr lens) ุ, which is the lens serves to expand the image to be. Then it has been extended with a picture to the screen, stretch the lens (lens projector) and adjust the focus of the electron particle beam to length to fit the glow appears on the scene. Finally, to create the image.
