History of JEOL Electron Microscopes,iba in Japan developed the electron microscope, respectively 1941..JEOL challenged developing EM, a little bit later. The birth of AD-1 EM, assembled on a wood table, was the debut of our company, JEOL. It was September 1947, a few years after the end of the Pacific War.

Introduction of the Electron Microscope,the transmission electron microscope (TEM) and the other scanning electron microscope, accurately speaking, scanning secondary-electron microscope (SEM). From the view point of vacuum technology, it is much difficult to evacuate the complex column of TEM to UHV, compared in the case of SEM. Therefor

Accidents and Information, Instructing Us to Improve the Vacuum Systems of JEMs,omer’s EM was, indeed, a most severe one for us, the vacuum engineers of JEOL. In that case the lead-glass window of the viewing chamber got gloomy after EM-film magazine was exchanged..Accidents and information on the vacuum systems of the JEMs always instructed us how to improve the vacuum systems

Development of JEOL SIPs, for the specimen chamber, and for the evacuation pipe to the diffusion pump. The SIP was apparently dedicated for the Philips EMs. We had to develop the JEOL SIPs dedicated for our JEMs, as Philips did. We must develop two types of SIP, one having high pumping speeds in ultrahigh-vacuum region, and
