Electron Microscope

An electron microscope uses a beam of electrons to magnify objects that are much too small to be seen with a traditional optical microscope. It has the unique capability of magnifying objects up to one million times their actual size, allowing us to observe microscopic features of cells and molecules that would otherwise remain invisible to us. This has allowed us to explore new domains of science like nanotechnology, materials science and biotechnology. Electron microscopes are also used for many other purposes such as examining insects, for diagnosing diseases and for identifying materials.
