Beamsplitters/Shapers?

[Dr.K]

I don't really know exactly what to call them as I am relatively new to lasers. I have seen things that come with little kiddie lasers that when screwed on show: smiley faces, dollar signs, hearts, etc......

I was wondering where to get things like these for my greenies.

Maybe a circle shape would be cool, or better yet some thing that caused the beam to have more divergence (look like a bigger beam), or even a line, like on these laser wall levels.

Is there a source for these or am I :thinking: just lost?

thanks,

The only time i've seen lasers do stuff like project hearts, $, smiley faces etc has been with purpose built lens attachments. A good alternative is external lens such as diffraction gratings.

Try these guys for a decent range of diffraction gratings http://store.rainbowsymphonystore.com/
