I know they sell different window diffusion materials that come in a sheet form that can be used. I'm just not sure on what they call them.

You could look to use a diffuser for a fluorescent light fixtures (Search google images for "fluorescent light diffuser panel"), I know they sell these at home depot. They might be a bit tricky to cut to size, maybe a glass cutter would do the trick? I ended up purchasing a piece of semi-opaque white plexi from a local glass shop cut to size. It wasn't cheap but works great.
