Differences in application between upright and inverted metallographic microscopes
The difference between upright and inverted is simply that the upright sample is placed below and the inverted sample is placed above. The upright objective is facing downwards, and the inverted objective is facing upwards.
Inverted metallographic microscope, due to the fact that the observation surface of the sample coincides with the surface of the workbench, and the observation objective is located below the workbench for upward observation, this observation form is not limited by the height of the sample. When preparing the sample, only one observation surface is flat, so it is commonly used in factory laboratories, scientific research institutions, and universities for teaching. The base of the inverted metallographic microscope has a large supporting area, a low center of gravity, and is stable and reliable. The eyepiece and supporting surface are tilted at 45 ℃, making observation comfortable.
The upright metallographic microscope has the same basic functions as the inverted metallographic microscope. In addition to analyzing and identifying metal samples with a height of 20-30mm, it is more widely used in transparent, semi transparent, or opaque materials because it conforms to human daily habits. An upright metallographic microscope forms a positive image during observation, which brings great convenience to the user's observation and discrimination. In addition to analyzing and identifying metal samples with a height of 20-30mm, observation targets larger than 3 microns but smaller than 20 microns, such as the surface structure and traces of materials such as cermets, electronic chips, printed circuits, LCD substrates, thin films, fibers, granular objects, coatings, etc., can all have good imaging effects.
