13,500 Lines/inch Diffraction Grating Sheet - Double Axis [1' x 6"]

I got the diffraction sheet to make silicone molds. Didnt have any problems just remember to check what side your using. One side is more dull then the other and has less of the diffraction then the other side...use the brighter side you wont have a problem. If you have finger prints on it...just take some rubbing alcohol with a micro fiber cloth and gently rub the print off works prefectly and it wont ruin the sheet.

The media could not be loaded. We put the film over some light up glasses. We just cut out the shape and used double sided tape to stick them on and they were so awesome. This particular film was actually VERY strong compared to the glasses you but already made so used at your own risk lol

I couldn't tell what side had the grating since both felt smooth to the touch. I used the wrong side for chocolate then I tried to wipe it clean but it already had oil from my failed attempt and I couldn't get it to work. Washing it lightly didn't help I messed it up

The package came early which is a good thing but I was disappointed in the single half sheet. Note it's my fault for not reading closely

I like the product...this is 2nd or 3rd time I purchased one. This one didn't have a piece of cardboard and even though it said "Do Not Bend" the mail folded it so it came with a crease in it. I'll make it work though.Still happy.

Although the film refracts light well, but the dents and kinks on the surface was a bit of a disappointment.

What I needed this for, I could not use with the dents & imperfections that were in this film. I tried but it didn't work out.

I used the sheets to make holographic chocolate. So long as I melted the chocholate properly (3/4 times), it worked great!Also produces ‘rainbow’ light defraction and splits laser beams as predictably would.Check the measurements before ordering. It fit my needs, but are a bit small.
