Where do I get A Line Diffraction Grating?

[Krogith]

Where do I get A Line Diffraction Grating? Looking for a glass square I can shot a few different lasers through... If this is a realistic thing.... Thanks for the help

Something like this?

Diffraction Gratings :: Dragon Lasers

What exactly are you looking for?
A diffraction grating that has the single diffracted beams on one line, or a line generator module (which is not a diffraction grating, but a cylindrical lens).

Both you can get from Dragonlasers:
Line Generator
Diffraction Grating

I hope this helps :yh:

if you are looking for a place to hack some low-power low-resolution diffraction gratings, you can take the backlight out of some old LCD screen.
