I do know that, at least, one can NOT see through the plastic wall with common IR devices, so I am guessing it is at least opaque to about 950 nm but that is only a guess. Did they (Patterson) ever address this problem/potential problem themselves? Ray BTW Anyone know which tanks are certainly NOT safe for IR processing? ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
