Hello all, so I tried to search the forums but was having difficulty finding a thread discussing diffraction gratings. I'm interested in getting some and some prisms to play with but I'm really unsure where to find gratings that can handle higher power lasers 100mW-5W
I was really interested in getting a grating set similar to the one posted on the dragon lasers web page for their 589nm lasers but sadly they no longer offer diffraction gratings.
I have all but 3 of the Sanwu Pen lasers and some of there higher power lasers.
Can anyone given me any recommendations on where I can get a good gratins/prism set? Thanks

Wow, that's bad news; I was just about to point you to Dragon Lasers for their diffraction gratings, that's where I've always purchased mine, I wasn't aware that they no longer sold them. :(
I'll be following this thread to see what other options are available these days; Dragon Lasers diffraction gratings were a decent product at a reasonable price.

Have you tried Edmund Optics... after all, you did say good.

You may also give a try on these small glass gratings offered on eBay....

Surely no lab quality like Edmunds

Actually, the plastic gratings work just as well as the glass ones for lasers up to 7 watts. You don't HAVE to go with glass for this.
