A method of scanning electron microscopy (SEM) of nonconductive specimens, based on measurement and utilisation of the critical energy of electron impact, is described in detail together with examples of its applications. The critical energy, at which the total electron yield curve crosses the unit level, is estimated on the base of measurement of the time development in the image signal from beginning of irradiation. The method is programmed and implemented as a module to the controlling software of the microscope type VEGA, where it secures fast search for the critical energy value.
