Sorry, but I forgot to list that they also have 6"x200' (yes, 200 feet!)
rolls of diffraction grating film.  I know you reqested 12x36, but if it's
area total (within a diffraction of an inch!) and not a certain size you're
going for, this might be of use:

I'm looking for a good source for diffraction grating film.
Edmund, Carolina and Arbor Sci carry only little sheets.  Web searches only
dig up manufacturers of precision and custom diffraction gratings for
specific optical applications in technical industries.
I just want a run-of-the-mill (?) diffraction grating.  I could use a
12 inch by 36 inch piece, and then some.

Thank you in advance,
Jason
