Variants
4 Variants of the EM9 are currently known to the author, these are the original EM9 as seen in the first image and promotional picture above. As well as the EM9A, EM9S and EM9S2. It is currently unknown what the differences between the EM9S and EM9S2 are. Furthermore based on the images provided, the EM9 and EM9S appear to be the same machine, but with a different name, what was changed between these 2 version is thus unkown.
EM9
This is the first generation of EM9, unlike later versions, it did not feature a condensor lens, instead opting for the use of direct illumination by the electron gun.
EM9A
This the second generation of the EM9, now featuring a 1 stage magnetic condensor lens.
EM9S
The EM9S appears, based on the image from Meeks book "Practical Electron Miroscopy for the Biologist, First Edition" to be externally nearly identical to the earlier EM9
EM9S2
It is not known if a EM9S existed, but the EM9S2 is presumed to be the successor to the EM9A
