Wow that is cool. Wish i had known that before i ordered mine from Anchor Optics - Holographic Diffraction Grating Film has anyone ever used these before? I think i might go wal-mart hunting tomorrow.

No, not this time, EF. I was looking at the ceiling light through the pattern and what I saw can only be described as a barcode if I were on LSD.

Go to LOWE'S in the CHRISTMAS decorations section. They have DIFF. GRATE. GLASSES in 4 different styles @ $2.00 a whack. So, for only $8.00 you can have 4 different DIFF. GRATES. GREAT DEAL................rob

Are they two axes or just one? Any idea of lines per inch?

 

[phoenix77]

I have no idea. I saw them on the way out & didn't have time to try any of them on, sorry..............rob
