1, binocular stereomicroscope is widely used in biological and medical fields for slicing and microsurgery; It is used for the observation, assembly and inspection of micro parts and integrated circuits in industry.
2. Metallographic microscope is a microscope specially used to observe the metallographic structure of opaque objects such as metals and minerals.
3. TV microscope and charge-coupled microscope are microscopes with TV camera targets or charge-coupled devices as receiving elements.
4. Scanning microscope is a kind of microscope whose imaging beam can scan relative to the surface of an object.

Precautions:
1. In the experiment, the microscope should be placed slightly to the left of the desktop, and the mirror base is about 6 ~ 7 cm away from the edge of the desktop.
2. Turn on the light source switch and adjust the light intensity to a suitable size.
3. Turn the objective lens converter so that the low-power mirror faces the light hole on the stage. First, adjust the lens to a distance of about 1 ~ 2 cm from the objective table, then look into the eyepiece with your left eye, then adjust the height of the condenser and adjust the aperture stop to the maximum, so that light can enter the lens barrel through the condenser, and the field of vision will be bright.
4. Place the glass slide to be observed on the stage, so that the observed part of the glass slide is located in the center of the light hole, and then clamp the glass slide with the specimen.
5. Observe with low power lens (objective lens 10x, eyepiece 10X). Before observation, turn the coarse focusing handwheel to make the stage rise and the objective lens gradually approach the slide. It should be noted that the objective lens should not touch the slide to prevent the lens from crushing the slide.
Then, look at the eyepiece with your left eye, don't close your right eye at the same time (get into the habit of looking at the drawing with your eyes open, so that you can look at the drawing with your right eye at the same time), turn the coarse focusing handwheel, and slowly lower the objective table, and soon you can see the enlarged image of the substance in the glass.
6. If the object image seen in the field of vision does not meet the experimental requirements (the object image deviates from the field of vision), you can slowly adjust the moving handle of the stage. During the adjustment, it should be noted that the moving direction of the slide is just opposite to the moving direction of the object image seen in the field of vision. If the object image is not clear, you can adjust the fine focus handwheel until the object image is clear.
7. Generally, for microscopes with normal functions, the low power objective and the high power objective are basically in focus. When the low-power objective lens is used to observe clearly, the object image can be seen by replacing the high-power objective lens, but the object image is not necessarily clear. You can adjust it by turning the micro focusing handwheel.
8. Replace the high-power objective lens, and after seeing the object clearly, you can adjust the size of the aperture stop or the height of the condenser lens as needed to make the light meet the requirements (generally, when replacing the low-power objective lens with the high-power objective lens, the field of view will be slightly dark, and the light intensity needs to be adjusted).
9. After the observation, move the objective lens away from the aperture, then adjust the aperture stop to the maximum, and then slowly lower the stage to check whether the parts are damaged (pay special attention to check whether the objective lens is stained with water or oil, and if it is stained with water or oil, wipe it with lens paper). After the inspection, you can pack it.
