Pol He-3 Rotation Stages

The camera snapshots are to roughly verify that the rotation stages are where we think they are.
This is done by looking at the relative location of the marks outlined in red.  One mark is on 
the rotating portion, the second on a fixed part of the rotation stage.

  • Note that the camera must be ON
  • Note that the camera is sensitive to the laser light as well. Try turning off all but one laser and adjusting the power until you can clearly see the marks noted on the images in the snapshots.
