Pack of 5-1Ft x 6" Diffraction Grating Roll Sheet Double Axis 13,500 l/inch - 5 separate sheets

I purchased these diffraction films to use as prisms to cast giant rainbows on my wall, they worked perfectly for that purpose!

Glued one to my 3d printer bed to transfer the pattern onto the prints.

Item came rolled, no finger prints, not crinkled, in perfect condition! Thank u!

Used it to make lenses for children's rainbow glasses.

I cut and placed two layers in a pair of safety goggles for health class, making them similar to "drunk" goggles. Worked well, fingerprints are easily made handling these.
