Could a DVD burning laser make scratches in, say, a sheet of transparent acrylic, like this?
Also looking for ways to make diffraction grating film and similar stuff.
- wbeaty 4y agoIt needs to make a polished groove or smooth surface-divot. Definitely use colored or black plastic, to promote surface-absorption. The real key is to eliminate jaggies. Either your steppers need micron resolution or better, or the laser-sweeping needs adjustable radius (smooth curves, but stepped depth.) I tell people, if you could play the hologram on a record turntable, the scratches must be silent. No micro-wiggles. The must behave as long, curved mirrors.
- ben_w 4y agoIIRC, no, because the edge that makes isn't sharp enough.
- ta988 4y agoit may if you focus it properly. Acrylic melts really well with IR lasers this may be easier they are cheap.
