Structure and function of the electron microscope
German physicist Ernst Ruska is most known for his invention of the electron microscope. The wavelength of the electron can be up to 100 000 times shorter than that of visible light photons. They can be used to view much smaller objects than classical optical microscopes. They can achieve magnification up to 10 000 000x.
