My investing idea in this issue is FLIR Systems, a global leader in thermal imaging. The company’s name is an acronym for Forward Looking Infrared, a kind of imaging technology that allows military aircraft and vehicles to see through darkness (and also daytime fog and smoke). Government Systems applications may be FLIR’s calling card, but they’re a small part of the whole story. The company also has a Thermography division that designs and manufactures temperature sensing technologies that can spot overheating machinery, leaks, flaws in buildings and gradients in scientific experiments.
