Electron Scanning Microscopies (ESMs) are powerful tools used in many different fields to observe, analyze, and understand the structure of materials, cells, and more. However, there are several antonyms for this term. Firstly, there are various types of microscopy that do not use electrons, such as optical microscopy or Atomic Force Microscopy. Secondly, scanning may not always be necessary; some microscopes, known as transmission microscopes, do not scan across a surface but instead focus a beam of electrons through a specimen. Finally, while the term microscopy implies observation on a small scale, macroscopic techniques like CT scanning or magnetic resonance imaging may be used to visualize larger-scale structures.
