OPTICAL EFFECTS AT METALLIC AND NONMETALLIC MATERIALS MICROSCOPY
Optical effects arising on surface defects of metals, alloys and transparent materials are discovered in conditions of various illumination such as dark-field and bright-field illumination as well as polarized light. It is shown that the methods of optical contrasting let it possible to determine su...

| description | Optical effects arising on surface defects of metals, alloys and transparent materials are discovered in conditions of various illumination such as dark-field and bright-field illumination as well as polarized light. It is shown that the methods of optical contrasting let it possible to determine surface defects of metallic and nonmetallic materials as well as defects inside optically transparent materials. The connection between optical effects and design features of lens by the use of dark-field illumination was shown. It is established that picture generation of spherical defect came about by analogy to uniaxial crystal by the study using polarized light. The schematic diagram of optical effects for various materials to make visual classification of surface defects is suggested. |
