I've been looking on the internet all morning And I can't find what I want.....

I want a diffraction grating that I can use with my 1 watt laser...

Where do I buy this at???? Do I have to buy from overseas???

I have bought the ones from o-like and they didnt melt
with my 1.2W laser.

Yes. The ones from 0-like are glass so they won't melt. But they are only 5mm x 5mm (pretty small). Oh, also all 10 of them in that pack are the same (starfield) pattern [just dots], I think.
I would recommend getting the 5-different pattern diffraction caps from o-like or the ones from laserlands. This will still yield 10x 5mm diffraction gratings, but they all won't be the same. You will get the circles, fan, plus, and starfield, but you have to extract them from the little diffraction caps (2 per cap). :eek:

(2 per cap) .... do you have to have the 2 together for them to work correctly??

I'm so glad that you said that because I ordered the 5 caps instead of the glass ones!!!!

Right after I order them I was like fuck will they meant???? Lol

I have a cheap 12$ laser pointer off ebay ..... I signed it threw that the grading cap...and it started so smell like burnt plastic!!!!! It still worked but I figured I better buy some good ones......

I think he wants diffraction gratings that won't melt with 1W laser. :D

Erm

Not really knowing any better, I've used a plastic diffraction grating quite a few times with my (measured) 1.8W 445. (Yob Build)

I haven't seen any melting, or distortion happening on it.. But I do make sure there's no specks of dirt or anything on it first (dark spot + high energy laser = lots of heat)

YMMV.
