Sounds like FLIR do not want the hassle of the red tape on such a low value item when selling to individuals. Understandable and this would likely also be the case for companies like Mouser, Farnell, RS and Digikey. The admin staff time has a very real cost for such companies.
A pity but let us not miss the fact that it is only a 80x60 core. It would seem logical that FLIR also have a 30fps 160x120 core as well
A Lepton 4 with at least 320x240 would be interesting
The Therm App appears to have set a high benchmark for image quality from a phone mounted camera, but at a cost. They also offer a 25fps version but ITAR red tape applies. I would certainly consider buying a Therm App if I did not already have a decent quality camera or two to use.
