Good morning from Germany,
we have an unknown problem with the alignment of the mirrors of one of our China Lasers. In the picture you can see laser focal points from all 4 corners. Three of them are almost on top of each other, but one is far away. Looking at the laser from the front, it is the upper right corner. We have aligned the axes and they fit, but we just can’t solve this problem. If we want to bring the upper right corner closer to the point of the lower right corner using mirror 1, the point from the lower right corner moves parallel. Due to this extreme shift, the laser power towards the upper right corner decreases vehemently.
Do you have an idea what could be the reason for this? With our other lasers we never had this problem. We have already tried for 2.5 hours today, unfortunately without success.
