Plastic thats invisible to IR light?
May 20, 2009
There are lots of great and interesting little robots on this site and on the web, but so many of them use the sharp IR detectors that they all start to look the same. I wanted to do something different and a bit more aesthetically nice, so I thought what if I could get some plastic thats transparent to IR. Then I could hide the IR sensors behind them and completely change the look.
The dome lenses on cheap PIR detectors are clear to IR but they aren`t big enough for what I want. Does anyone know where I can get this stuff, or even what the technical name for the plastic is? Maybe there are some plastic things around the house that could be used. Or some paint that passes IR but not visible?
