Yuefan and Yuhang

This morning we installed everything for the AA telescope before opening the chamber.

The final beam height is 225mm from the bench. All the optics position are only followed the design, we didn't have time to connect all the cables to check any signal. The second lens is installed on the rail, galvo and quadrants are all installed on the height changable posts.

The FF path is well aligned, the beam is hitting in the center of the quadrant. But the NF path, we still need to adjust a bit the mirrors of the galvo, to make the output beam on the same height and without any angle. It was not very easy to do because the position of the galvo is almost in the center of the bench.

The detail pictures are in the attachment. I found it was difficult to take a picture that shows all the components....I should also have taken some pictures from the other side of the bench, I will put them later...
