Phase microscope is a precision optical instrument for industrial inspection. If you are a novice who has not been exposed to it before, you generally don't know how to use it. Today, I will tell you the steps to use the metallographic microscope.
Before using the metallographic microscope, you need to make the sample into a smooth mirror surface. Most materials need to be corroded before you can see the internal structure clearly. I won't talk about how to make the sample today. There is also an introduction to this in the previous article. After making the sample, you can take it under the metallographic microscope for observation. The following are the steps to use the metallographic microscope:
1. Connect the power supply, turn on the switch, and adjust the brightness of the bulb to a comfortable state for observation.
2. Hold the left and right eyepiece seat rotation axes and rotate to adjust the pupil distance so that the image seen in the left and right eyepieces is a circle. In this way, the pupil distance is adjusted and it is more comfortable to look at.
3. Select the objective lens magnification to be used, and rotate the objective lens to use. Generally, use the low-power objective lens to find the image at the beginning.
4. First rotate the coarse focus handwheel to find the blurred image, and then use the fine focus handwheel to make the image clear. If you want to observe images in other areas, you can adjust the horizontal adjustment hand wheel on the table to change the field of view.
5. After using the metallographic microscope, first adjust the brightness of the bulb to a dark place, and then turn off the switch, so as not to affect the service life of the bulb. Then unplug the power supply and cover the protective cover to avoid dust.
The operation of the metallographic microscope is not difficult, and you will learn it after using it several times. There is no need to be afraid of damaging the metallographic microscope, just be careful not to touch the eyepiece and objective lens with your hands.
