Optics and laser accessories

I was wondering if anyone knew of any good companies that carry things like prisms and lenses as well as any other laser accessories in general. I know a lot of the popular companies that sell lasers have a few things like this but I'm looking for a better selection. Any and all recommendations are appreciated.
:thanks:

Thanks this is just what I've been looking for. I have a lot of stuff already but my kit is not yet complete and a lot of optics products are just so expensive.
More recommendations are welcome.

O-Like has 10 diffraction gratings that are sweet for $8 bucs... they are very tiny, but hold up to heavy hitter lasers.

Those are fun for the whole family!

Don't ask for rep...

Before I read that part, I was actually going to +rep you.

InfinitusEquitas - Hehehehe! No you weren't!

sopark4000 - You can stack and rotate/counterrotate them to get cool effects. But you probably already know this. But, for those who don't...

Check out what this dude (member?) did with some advanced, motorized legos and diffraction grating (if you have seen it before hold your urge to say so):

The gratings he has are thin plastic sheets and don't stand up to strong lasers for long (could be wrong), but are easy to apply. The ones on o-like are so small they will have to have precision mounting, but you could make a really small kaleidoscope.
