The electron microscope uses a beam of electrons controlled by a system of magnetic fields.
With the electron microscope belonging to the INRS-Institut Armand-Frappier, it is possible to obtain magnifications up to 600,000 X on the main screen but with a television camera, a magnification of 12,000,000 X can be reached. Furthermore, by increasing the height of the column, higher magnifications can be attained. With supermicroscopes, one can even see macromolecules.
Depending on the focal lengths chosen, one can obtain magnifications between 1,000 and 600,000 X and even more with high yield microscopes. The image can be further magnified (8-10 X) with binoculars or a television camera (20 X).
