Hi All, Newbie question, any help would be greatly appreciated

Hi,

Sorry to have my first post be in a new thread but Im desperate for some guidance. I am looking to build a laser to project my very simple logo through a diffraction grating so my single colored logo is scattered all over the back of a 10' wide wall. Can anyone here steer me in the right direction to get this done? Any help would be immensely appreciated.

Thank you,

Dan

If you're needing a diffraction grating making I suggest you start here http://www.triple-take.com/home.html

You'll need to speak to Dinesh or joy.

I can't imagine a 'one off' being particularly cheap though.

Cheers

If you can scan your logo - throw the diffraction grating of choice after the scanner. If you want to brute force the logo use a beam expander to get it to the correct diameter - if the logo is significantly rectangular build up a beam expander with cylindrical lenses for efficiency. Or use a lumia wheel with a single "rippled" surface and focus the laser on the single "rippled" surface to get as close to a point source as possible. If this is for a serious marketing campaign with $$$ budgeted talk to DSLI_jon - he's got something new that's impressive and would be perfect.

i would certainly suggest a system using using a set of galvo scanners with a diffraction grating scan through.



alternatively, it would be pretty trivial to laser/waterjet cut a gobo that you can shine your lasers through.
