We performed several scans of the the z positions of the translation stage or the IU with the surface reference sample.

We plan to check if the shape of these signals could be used to perform more efficiently the alignment.

We tried to place back the PBS for the birefringence measurement but it was quite lossy (~20%).

Actually the one we used does not have name but the holder height seems to match. So we installed it as in entry 1496.

I'm planning to buy a new PBS as I could not find other.

The R_surf is now 16.79 /W at z_translationStage = 40.5 mm and z_IU = 66 mm.

Tomorrow we'll start the absorption measurement of the korean sample.
