Environmental Scanning Electron Microscopy
medical dictionary



Scanning electron microscopy is performed by scanning a focused probe across the surface of the sample to be studied. In the environmental scanning electron microscopy the composition and pressure of the atmosphere around the specimen may be controlled. In favourable cases non-conductive specimens may be examined without coating, and hydrated specimens may be examined with the water still in place.
