Some particularities of microscopic investigation of non-metallic objects

The article deals with the comparative application of optical and raster microscopy for non-metallic objects and non-conducting surfaces. It is noted that this issue is not covered much in the special literature. There are practically no publications that compare and describe photos of the structure of materials obtained using fundamentally different microscopes, in particular, metallographic and raster. The causes of image distortion in a raster electron microscope in the study of dielectrics are considered. Comparative images of the oxidized surface, fabrics and natural leather obtained using raster and optical microscopy are presented. The advantages of optical microscopy in the study of non-conducting surfaces are shown.
