This lecture introduces the components of an electron microscope, including optical elements, detectors, and the vacuum system. Topics covered include electron-matter interactions, types of electron microscopes (SEM and TEM), vacuum systems, and electron gun systems. The lecture also discusses the importance of vacuum cleanliness, different types of vacuum pumps, and the consequences of using electrons in microscopy. Various aberrations in electron optics, such as spherical aberration and chromatic aberration, are explained. The lecture concludes with a detailed overview of electron detectors, specimen holders, and useful literature in the field.
