| Summary: | The optical effects which appeared on internal defects of optically transparent materials by use of various methods of optical staining, i. e. dark-field illumination and polarized light were researched. It was shown that methods of optical staining support to determine spherical defects under a surface of optically transparent materials. Formation of optical effects on materials defects in dark background are partially determined by design features of microscope objective and it was found out. It was defined that the investigation using polarized light the image formation of spherical defects occurs similar to uniaxial crystal. |
