WITH ATOMIC PRECISION
In 1955 , Strojnik designed and constructed his first electron microscope in Ljubljana , the LEM1 , making Yugoslavia the fifth country in the world not only to have its own electron microscope , but one that was the product of domestic
know-how . Established by Strojnik , the Electron Microscopy Laboratory would in the subsequent years produce a series of electron microscopes , named LEM1 to LEM4 . The latter was the first such device in the world to be air-cooled .
