added HWP in front of AlGaAs coating

To confirm our AlGasAs birefringence measurement, we want to add a birefringent component between the BS and the coating.

I placed the HWP that was measured before (same roll angle as before).

Measurement from 0 to 3.5V with 0.1V step, LC temp is 30degC, 100 average and 1s wait time.

There is no requirement to switch on wait time for any measurement. There is already an intrinsic wait time present in the labview logic. The external wait time is only to be switched on if you are doing stability measurement of the setup(for >~a day) and don't want to take measurement with high frequency. Unless there is a promising reason there is no use of switching on the external wait time for birefringence measurement of samples.

Restarted measurement without wait time and same parameters otherwise

by mistake the first few points were saved in the previous file..

I stopped the vi and restarted maesurement C:\Users\atama\Dropbox\LC-Experiment\Measurement Data\Coating measurement\AlGaAs\with hwp\Mon, Jun 24, 2024 2-27-30 PM.txt
