The transmission electron microscope (TEM) is a scientific instrument that uses electrons instead of light to scrutinize objects at very fine resolutions. They were developed in the 1930s when scientists realized that electrons can be used instead of light to "magnify" objects or specimens under study. TEMs provided a means to go beyond the magnification and resolution limits of light microscopes, allowing for magnification of up to 100,000x and resolutions in the nanometer range. Uses of the Transmission Electron Microscope The TEM has its primary uses in metallurgy (or the Read More
