Katsuki-san, Marc

This morning we went to PCI to check the ATEC sample.

We found out that the peak visible in the polarization angle measurement is likely due to a dust so we removed it. Except that the sample seems perfectly fine.

We brought a laptop with Kinesis installed and connected it to the motorized HWP.

We got the same issue as with the PC (only jog by 1 deg).

We tried to home it and will check after lunch.

If problems persist we will contact Thorlabs and switch the 2 motorized HWP as the other is working fine.
