WebScanning Electron Microscopes work pretty much the same way that optical microscopes do. In an optical microscope, light is emitted onto a sample. That light reflects from the sample and is captured, focused, and magnified by lenses. Optical Microscope (left) vs Scanning Electron Microscope (right).
Many developments laid the groundwork of the electron optics used in microscopes. One significant step was the work of Hertz in 1883 who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam.
