The problem of imaging astigmatism has always been one of the reasons that restrict the precision of image measuring instruments. In different research centers of manufacturing enterprises, they are concentrating on this problem. So what is the problem of astigmatism of image measuring instruments? Handling it will be the focus of our soft paper.

In actual operation, after starting the switching power supply, if the shadowing is not concentrated on the large screen and the resolution is low, we call it the astigmatism fault of the image measuring instrument. At this time, the objective lens is updated anyway, or the measuring angle is changed. On the big screen, it is still the same picture. At the beginning of this situation, many people don't know much. They think it is caused by dirt on the lens. The result is wiped by hand. The effect is counterproductive and the picture becomes More unclear. After reading this article, first confirm whether it is caused by astigmatism.

If it is determined to be after the astigmatism failure. First, turn off the power, fold the body of the image measuring instrument, and replace the LED mounted on the lamp holder. It is likely that the LED is not concentrated. Replace the LED and restart Whether the power supply problem still exists. The general situation is almost the same. Secondly, remove the boot and check whether the mirror of the glass is even. Evenly, the split will not astigmatism. If the unevenness will lead to astigmatism, it will lead to astigmatism.
