realignment

Katsuki-san, Marc

In order to mitigate the misalignment induced by the sample, we decided to move the 2 PDs closer to the waist.

For that, we also needed to change the ODs mounts for a smaller one.

We confirmed that with the realignment the maximal power of s or p polarizations with sample is smaller than the maxima without sample.

We started measurement with s polarization at input and the AZTEC sample rotated by 180 deg
