Whether or not 3M material was used in the kit mentioned, the suggested
solution sounds quite reasonable and is probably far cheaper than the one i
put forward in a previous post. And of course, both solution equally much
do away with the need for narrow-band filters. If the Scotchlite approach
works in practice is a different question, but the experiment needed to
find out should be simple and inexpensive.
