+Our light sources take on horizontal or vertical polarizations according to which tuning process is
+used. %
+Our experiments are opinionated about polarization, so some strategy for aligning polarization is
+necessary. %
+Desire fully reflective, easy to switch without changing path length (delay) etc... For several
+years, we used brewster-angle polarization unifiers... %
+These worked by... %
+But these were very difficult to align, and they were too lossy for some of the weaker tuning
+processes. %
+As an alternative, we designed a more traditional periscope with adjustability for our unique
+needs. %
