Such thermal investigation would be a challenge as the temperature differential inside the Micro-bolometer FPA is intentionally very small. The sensing elements do not produce heat. The resolution of the FireFlIR (320x240) is also too low for die detail, even when using a close-up lens.

Yes, but you could potentially hold a "light" (soldering iron?) over it and see differences in thermal reflectivity on the microbolometer.

Next time I have it apart, I will try with a halogen lamp

If needed, i can send you a 600W HPS plus ballast. That should give you enough heat and light  :-DD

Greetings,

I found an interesting and enlightening document on Microbolometer design that had Inframetrics input. I have placed it under its own heading here:
