Scanning Electron Microscope - Research University | Purdue University SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes have developed new areas of study in the medical and ...
How Scanning Electron Microscope (SEM) Works | SEAL Labs The Scanning Electron Microscope (SEM) was developed mainly because of the limitations of optical microscopy. These limitations are caused by two inherent factors involved when using light. Microscopes: The first is the rather large wavelength of visible
