Decoder Glasses

[teniworks]

I wonder if anyone else has had to do this but, we are going to produce our own decoder in-house and I need to find the actual decoder film. The only thing I have been able to find so far is the cellophane material used in packaging which I think will be too thin. Or 3D glasses and decoder glasses. Does anyone know of a place where I can purchase the material only? Or can we use the packaging cellophane?

The material is called a color gel. Its often used in stage lighting for colors. http://en.wikipedia.org/wiki/Color_gel

You can purchase it from many theater and stage supply companies.
