Zeiss is a German Manufactuer of Electron Microscopes, much like Siemens it was involved in the invention of the Electron Microsocpe. Originally its development focused on the creation of Electrostatic microscopes, but this approch was later abbandoned in favor of the Electromagnetic lens.
Only 2 models using exclusivly Electrostic Lenses are currently known to have existed, this is the experimental EM7, and the production EM8 microscope.
The EM9 marked the first all Electromagnetic Electron Microscope constructed by Carl Zeiss.
