See my user name.
Laser Wavelength typically: 904nm +/- 10 nm
Good points Switch. I did a few tests with a film that blocked a high percentage of the IR in the police spectrum. It was not very effective. I think part of the problem was that it was reflecting a good amount back. While you can make a film specifically designed to absorb the IR, it was cost prohibitive to do a run of the film due to the relatively small market for it. Us speeders would only need very little of the film in contrast to how much film is used in commercial applications. My guess is that what you will find for sale out there is not purpose formulated to absorb police IR.
