	Possibilities of evaluation of the influence of conditions in the specimen chamber on the quality of imaging in environmental SEM Michálek, Martin ; Jirák, Josef This paper deals with the possibility of evaluating the quality of the image from the processing of the signal from the standard specimen in the line scan mode. The signal level, signal to noise ratio and angle of declination are suggested as parameters which can describe signal of electrons in environmental SEM. Detailed record
	Scanning electron microscopy at low vacuum in specimen chamber Autrata, Rudolf ; Jirák, Josef Observation of specimens at a low vacuum in the specimen chamber brings some advantages in comparison with observation in a high vacuum. Water-containing and electrically non-conductive specimens are of special significance. The principle of low vacuum microscopes and problems with the interaction of electrons with the gaseous medium are described. Detection of signals in the so-called environmental (low vacuum) microscope is realised with the help of a single crystal YAG scintillation detector of backscattered electrons on which an electrode system for ionisation detection of secondary electrons is deposited. Some examples of insulation specimens, wet specimens and biological specimens of soft tissues are presented. Detailed record
