The upright metallographic microscope includes two illumination systems, transmission and reflection, which are two light sources up and down. The upright metallographic microscope mainly observes cermets, electronic chips, printed circuits, LCD substrates, films, fibers, granular objects, The structure, traces, etc. of the surface of the coating and other materials, so the upright metallographic microscope is also called a multi-functional metallographic microscope. It is very suitable for scientific research units, because they have more data to study.

    Inverted metallographic microscopes are mainly used in casting, smelting, heat treatment research, raw material inspection or data processing analysis.

    The positions of the field diaphragm, aperture diaphragm, and light box, the field diaphragm, aperture diaphragm, and light box of the inverted metallographic microscope are all behind the objective lens, and the field diaphragm, aperture diaphragm, and light box of the upright metallographic microscope All are behind the eyepiece tube.

    The position of the stage, the inverted metallographic microscope stage is behind the eyepiece tube, and the upright metallographic microscope stage is in front of the eyepiece tube. If the sample position is not suitable for adjustment, the sample in front of us is easier to adjust. From this point of view, the upright metallographic microscope is more suitable for people's usage habits.

    The position of the objective lens, the objective lens of the inverted metallurgical microscope is below the stage, and the objective lens of the upright metallographic microscope is above the stage. Because of this, the inverted metallographic microscope has no limit to the height of the sample, while the upright metallographic microscope limits the height of the sample, and its height depends on the interval between the up and down movement of the stage, and the general height does not exceed 30mm. Therefore, it is more suitable for enterprises to use an inverted metallographic microscope for metallographic inspection, and it does not matter whether the sample is large or small.

    Another point is that the inverted metallographic microscope is to buckle the side of the sample to be tested on the stage, and only need to prepare the sample on that side. The upright metallographic microscope requires both sides of the sample to be viewed on a parallel line, and the sample preparation also requires two sides. From the perspective of sample preparation, it is also more suitable to use an inverted metallographic microscope, but although the upright metallographic microscope has high requirements for sample preparation, it is easier to find images. In short, both have their own scope of application.
