Default Re: Novice needing advise on projecting logo

You might not need a projector for this. If it's just a static image of a relatively simple logo, the cheapest way would probably be to get a custom diffraction grating made that creates the logo. Like this service for example: https://www.alibaba.com/product-deta...979340394.html

Not sure I'd trust those gratings to handle the required power...

I'm sure there are manufacturers that let you choose different materials that could handle it. There are first-contact reflective diffraction gratings out there too.
