An electron microscope is similar to a traditional microscope but uses a beam of electrons for higher magnification and resolution, enabling views at a molecular level.
A tool that performs a similar function to a microscope is the electron microscope. While a microscope ordinarily uses visible light and glass lenses to magnify objects, an electron microscope uses a beam of electrons and electromagnetic lenses for magnification. This difference allows electron microscopes to achieve much higher resolution and magnification, making it possible to view structures at a molecular level which is far beyond the capabilities of light microscopes.
