What are the differences between a light microscope a compound microscope a stereoscopic light microscope a transmission electron microscope and a scanning electron microscope? A light microscope uses a series of lenses to focus light allowing small objects to appear larger.
An electron microscope uses electrons to observe the structure and morphology of things at small scales (down to a fraction of a nanometer). The main types of electron microscopes are the Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and the Scanning Transmission Microscope (STEM). Electron microscopes have a wide range of applications in science and technology. To unlock this lesson you must be a Study.com Member.
