Caption:
This 1960 photograph depicted a laboratory technician who was seated at a transmission electron microscope (TEM), as she was analyzing the ultrastructural details of a laboratory specimen. A TEM works much like a light microscope, however, rather than implementing light waves as a means to illuminate a slide specimen, electrons are used instead. Traveling at a much lower wavelength, electrons enable the observer to see ultrastructural details at a resolution many times greater than when using light waves. Electromagnets are used as the lenses for this device, rather than glass lenses, focusing the beams of electrons through the specimen, which finally hit a fluorescent screen that scintillates when the electrons hit its sensitive surface.
