During the July 2012 test beam period, we brought a lead fluoride (Pb F2) crystal that did not show very much difference between response to beam particles with polarizers rotated between the favorable and unfavorable orientations.

Consequently we removed the crystal from the beam and made a manual check to see if polarization was preserved when polarized light was passed through the crystal from one end to the other. We also made the same test for light that passed through the sides of the crystal.

Videos of these two sets of tests are attached to this page.
