Imaging techniques have been instrumental in giving insights into the world beyond the naked eye. Scanning electron microscopy (SEM), which produces images of a sample by scanning the surface with a focused beam of electrons, is one such technique. Traditional SEM instruments have provided us with unprecedented details of every surface you can think of, from whole insects to crystals and bacteria, but can be complex to use, requiring specialist knowledge, and also require a large dedicated space. The dawn and advancement of compact and user-friendly benchtop SEMs however is changing this picture.
