Electron Microscopy : An Introduction (1963)

The film provides an introduction to electron microscopy, detailing its historical development and technical mechanisms. It highlights the evolution from light microscopes to electron microscopes, explaining how electron beams, with much shorter wavelengths than light, allow scientists to observe minute structures at unprecedented magnifications. The electron microscope operates in a vacuum, using electromagnetic lenses to focus electron beams on specimens, enabling the visualization of structures down to the atomic level. The film also discusses various applications of electron microscopy in fields like biology, materials science, and industrial research, showcasing its importance in understanding the ultra-structure of materials and biological entities.
