On April 7, 1931, Ernst Ruska was able to demonstrate two-stage magnified imaging with electron lenses for the first time at the TH Berlin, the predecessor of the TU Berlin. (Source ISSN 0001-5857).
For the invention of the electron microscope, Ernst Ruska received the Nobel Prize in Physics in 1986, together with Gerd Binnig and Heinrich Rohre (inventor of the scanning tunneling microscope).
ZELMI's service ranges from advice on microscopic examinations to evaluation and reporting of results.
The instrument-specific preparation is performed on site.
For general preparation of samples, we can assist customers who do not have preparation facilities themselves.
In addition, ZELMI also offers teaching as a service, consisting of lectures, practical sessions and hands-on training.
Furthermore, equipment is available on which service users can work independently after an introduction. Regular use is the prerequisite here.
