Orthogonal and inverted metallurgical microscope application differences
The difference between forward and inverted is simply that the forward sample is placed below and the inverted sample is placed above. The objective lens is placed downward in the forward position and upward in the inverted position.
Inverted metallographic mic roscope, due to the specimen observation face down with the surface of the table overlap, the observation objective is located under the table, upward observation, this form of observation is not subject to the limitations of the height of the specimen, as long as the preparation of specimens, as long as an observation surface flat, so the factory laboratories, scientific research institutions and colleges and universities teaching the common choice. Inverted metallographic microscope base support area is larger, lower centre of gravity, stable and reliable, eyepieces and support surface tilted at 45 ℃, comfortable observation.
Orthogonal metallographic mic roscope has the same basic functions as inverted metallographic microscope, in addition to the height of 20-30mm metal specimens for analysis and identification, because in line with the daily habits of people, so it is more widely used in transparent, semi-transparent or opaque substances. The orthogonal metallographic microscope has a positive image when observing, which brings great convenience to the user's observation and identification. In addition to the analysis and identification of metal specimens with a height of 20-30mm, it can also be used to observe targets larger than 3 microns and smaller than 20 microns, such as the structure and traces on the surface of metal ceramics, electronic chips, printed circuits, LCD substrates, thin films, fibres, granular objects, plating and other materials, with excellent imaging results.
