I replaced the newfocus 5104 with Thorlabs BB1-E03 mirror.

Actually, when I first checked the beam centering, I noticed that the beam was not centered on the 5104 mirror. The beam at this instance was at the center of the camera.

So, even though I changed the mirror, it was made sure that the beam was incident at the center of mirror, and the reflection was at the center of the camera. In, this process only the mirror was moved. All other components were left undisturbed.

The LC voltage scan was done from 0-25V for both with 0.02 resolution.
