How does the automatic image measuring instrument solve the problem of imaging astigmatism?
The problem of imaging astigmatism has always been one of the factors restricting the measurement accuracy of fully automatic image measuring instruments. Many research centers of manufacturing enterprises are devoting themselves to this problem. So, what is the astigmatism problem of the automatic image measuring instrument? How to deal with it? Next, MiaoJi will answer for everyone.
In actual operation, after turning on the switching power supply, if the image is not concentrated on the big screen and the resolution is low, we call it the image measuring instrument Astigmatism failure. At this time, no matter how to update the objective lens or change the measurement angle, the same picture is displayed on the big screen. At the beginning of this situation, many people didn't know much about it, and thought it was caused by dirt on the lens. As a result, I wiped it with my hand, and the effect was counterproductive, and the picture became more unclear.
For the above problem, we first confirm whether it is caused by the astigmatism of the automatic image measuring instrument. If it is determined that the astigmatism is faulty, the treatment method is as follows:
First, it is very likely It is caused by the LED not concentrating, turn off the power, fold the body of the automatic image measuring instrument, and replace the LED installed on the lamp holder. After replacing the LED, restart the power to check whether the problem still exists. Generally, it is almost the same. This is the reason.
Secondly, disassemble the base and check whether the mirror surface of the glass is uniform. Even the division will not cause astigmatism, and unevenness will cause astigmatism.
Through the above two methods, the astigmatism problem of the automatic image measuring instrument can generally be solved by cutting the bottom. For more questions about the image measuring instrument, welcome to consult Miaoji Precision, we will serve you wholeheartedly.
