Hi everyone. I was approached by a potential customer who has a unique application. He wants to etch designs onto small circular pieces of a material and then shine a light source through them to project the image.

It's similar to one of these laser pointer sets where each attachment projects a different image:


The only thing is that the projected image is magnified a lot so the edges need to be crystal clear. I tried etching on glass and acrylic but the edges are too grainy.

Does anyone know of a material I can etch an image onto and have all the clarity and detail there when it's magnified? The pictures are 3/8" diameter.

I was thinking of using Thermark LMC12 marking solution on thin sheets of polycarbonate plastic.

Can anyone help me out?

Thanks,
Nick
