S7 birefringence measurement

The beam in the reflection of beam splitter was tuned to remove the misalignment of the beam (beam height was chaning by 1cm at the end of the table). Now the beam height is same as before the BS.

I placed the Shinkosha S7 after the beam splitter reflection and before the camera. The LC voltages are changed from 0.5V - 3V with 0.25V step size, with 10 averaging.

The birefringence obtained is Fig 1. Since there were too few points (112/6050) after filtering. I will re take measurements.
