Scanning electron microscopes will always have such and other scanning electron microscope failures in the process of using, resulting in poor observation effects when observing objects. The following will teach you how to troubleshoot microscope failures.

So what kind of observation effect determines that the microscope is malfunctioning?

One is the blurred field of view of the microscope.

The second is that the double images do not overlap during microscope observation.

The third is to find that the image is still not clear when adjusting the eyepieces and rotating various angles.

Of course, in addition to these common failures, there are other phenomena, so when we encounter such failures, how should we eliminate the obstacles of the microscope?

When encountering these problems, be sure not to rush, as many microscope failures can be solved. For when the field of view is blurred or there is dirt, it may not be a malfunction of the microscope. The most likely cause is that there is dirt on the specimen. After removing the dirt on the specimen, if the observation object is still blurred, what's the matter? ? At this time, check whether there is dirt on the surface of the eyepiece, the surface of the objective lens, and the surface of the work board. These will cause blur when observing the object. These problems can be solved by wiping the eyepiece and the objective lens. If you are observing the microscope, you encounter the phenomenon that the double images do not overlap. At this time, the possible reason should be considered because the interpupillary distance adjustment is incorrect, or the diopter adjustment is incorrect, which can be solved by adjusting the distance between them.

In summary, when encountering failures such as unclear objects in the microscope, you must carefully find the cause, and at the same time eliminate the scanning electron microscope failures one by one. At the same time, it is also very important to accumulate experience in peacetime.
