Scanning Electron Microscope

A Scanning Electron Microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons. The electrons interact with the atoms in the sample, producing various signals that can be detected and used to create an image. SEMs are commonly used in the field of space and astronautical engineering to analyze the surface morphology and composition of materials used in spacecraft and other space-related applications. They can provide high-resolution images of materials at magnifications up to 500,000 times, allowing for detailed analysis of surface features and defects. SEMs are also used to study the effects of space environments on materials, such as radiation damage and thermal stress.
