I am looking for that dark red plastic that goes on IR remotes, so that the IR light doesn't become visible to the human eye. Alone, the IR LEDs I'm using give off a dim red color visible to the naked eye. I am wanting to cover it up with that plastic (PMMA ?) so it won't be visible to the eye, yet still let the IR light through.
Can anyone recommend a good website where I can order samples? I've found a few websites, but they all require either bulk orders, or the materials are rather big. I'm looking for a square foot or less.
(If you know other websites where I can get electronic and chemical SAMPLES, not a big order, I'd very much appreciate it.)|||Isn't there a craft store in your town? See if your camera can "see" the IR from your remote. (It probably can; keep trying cameras until you find one.) Then take the remote and the camera to the craft store, and see which of the black plastic sheets you can see the remote through. (If you don't care about looks, you can probably stay home and just cut up a black plastic garbage bag.)
Otherwise, Edmund Scientific is probably your best bet for small quantities.
