Introduction to Electron Microscopy
In 1924, a French scientist, Dr. de Broglie, showed that an electron beam behaved like waves and had a wavelength much shorter than the sizes of molecules and atoms when accelerated.
The first electron microscope was devised by two German scientists, Drs. M. Knoll and E. Ruska, in 1931.
During the1960s, many electron microscopes were manufactured in Japan.
Today, Japanese manufacturers account for a greater than 60% share of world electron microscope production.
The electron microscope is an indispensable tool for research in the biological and materials sciences.
