Summary: plexiglass and polarization.


Stressed plastics will do all sorts of weird things to the polarization
of a light source, which may or may not have any effect on picture
taking or using it in contact printers.  More likely is that
plexiglass is easier to deform into non-optically-flat surfaces.
