First I eased a bit the Map BIrefringence vi.

Several tabs were present which was great for readability but some times made it hard to have all information at once.

I removed the aztec 60 40 1 from the translation stage. Note that some arrow marking were present from delivery. The sample was aligned so that the arrow is at the top facing the laser source.

After waiting about 1h for laser to stabilize, I've started measurement of aztec 60 40 2 with same parameters as aztec 60 40 1.

No marking were present so I made a white dot at the top towards the laser source.
