Environmental scanning electron microscopy in colour

SUMMARY The environmental SEM has been developed to a stage where colour can be introduced during imaging. A new approach to production of colour micrographs is demonstrated together with some typical uses of the environmental mode of SEM. A combination of the outputs of two backscattered electron (BSE) detectors alone or in combination with the outputs from a gaseous detector device can form images corresponding to particular aspects of a given specimen. Two or more of these images can be superimposed on to the same colour print to produce a colour micrograph.
