I purchased one of the new FLIR E4 thermal imaging cameras (TIC) a couple weeks back because I am working on a new project called Motobrain . It is an automotive power distribution unit with a nominal current capacity of 100A. For those not in the know, 100A is a TON of current! Because this project is designed to move so much current and will be small I need to understand its thermal characteristics very well. To that end I've been operating the device and taking measurements. What I found is that I just could not get the kind of detail I wanted. The reason is that the resolution of the microbolometer in the FLIR E4 is not very high and the lens does not allow you to get very close to the device under test (DUT). The means that you cannot just zoom in after you take a photo either. So, what is a person to do if they want to take a macro photograph with a consumer grade TIC? Go to Amazon.com of course! I purchased a Gallium Arsenide (GaAs) lens meant for a CO² laser for about $4
