Siemens

The Siemens Logo as seen in 1971

The Siemens Corperation has, throughout the years produced many things, among them was the very First Electron Microsocpe. The history of the Electron Microscope started with Siemenes and Ernst Ruska, together with his research team, they created the very first Electron Microscopes.

Models

Siemens, as the company responsible for the invention of the Electron Microscope has produced many models throughout the years, also selling a rebadged version of the Etec Autoscan which was sold under the Siemens name outside the United States. Most of their models however where of the Transmission kind, mostly due to Ernst Ruskas Prescience.
