The article analyzes the methods of modernization of optical microscopes to obtain digital images and simplifies their subsequent
analysis while conducting basic metallographic examinations of deposited metal specimens. Two main methods of modernization
were considered: with the help of a camera, equipped with special adapters, which is attached to the tube of the microscope eyepiece
and with the help of a video eyepiece, which is installed instead of a standard microscope eyepiece. The main advantages
and disadvantages of each method were noted. Using MIM-7 metallographic microscope, Canon 650D camera, SIGETA MCMOS
3100 video eyepiece, as well as specimens of microsections with a deposited layer of semi-heat-resistant steel of C – Cr – Mo
– W – V alloying system, comparative metallographic examinations were performed. It is shown that the use of a special video
eyepiece SIGETA MCMOS 3100 allows obtaining better digital images of metal microstructures. As an illustration of the main
advantages of the work, provided by the use of the equipment modernized in this way, the results of metallographic examination
of metal, deposited by electric arc method using flux-cored wire PP-NP-120V3KhMF, were provided. It was experimentally established
that the Toupview software, supplied with the eyepiece SIGETA MCMOS 3100, used in these examinations, allows easy
processing of the obtained digital images, which greatly expands the capabilities of basic metallographic analysis. 10 Ref., 7 Fig.
