The Elmiskop II was a medium end Electron microscope manufactured by the Siemens Corporation. It was somewhat based on both the design and technology of the Elmiskop I which proceeded it.
Unlike the aforementioned Elmiskop I, the Elmiskop II was a much simpler, and thus much less costly machine. Instead of the Elmiskop I's 5 Electromagnetic lenses, it only Featured 2, namely the Objective and a Projective lense furnished with a pol piece revolver. This revolver allowed the microscope to change magnification in the absence of an intermediate lens, as is featured in almost all microscopes fallowing the ÜM100. The illumination system consisted merely of a simple triode Electron gun similar in design to that of the Elmiskop I. Much like that of the Elmiskop I, it also featured full adjustments and mechanical beam tilt, however it lacked the Stigmator seen in its bigger brother.
History
The Elmiskop II started as a project by Ernst Ruska and K. Müller to develop a more economical alternative to the Elmiskop I, yet allowing, much like microscopes preceeding it, to use at least some accesories of its predecesors and or brothers. It also used the tried and true vacuum system found within the Elmiskop I as well as a good deal of its castings, thus lowering production cost.
First mentions of an Electron Microscope fitting the description of the Elmiskop II where first seen in the paper tittled: "Ein vereinfachtest Elektromagnetisches Durschstahlungsmikroskop für Elektronen von 40 bis 60KV*)[1], where it was not reffered to by name as the Elmiskop II, but its technical design was very similar, thus leading to the conclusion that it was later developed into what is now known as the Elmiskop II.
