Have fun with the melexis unit. Though it appears to be 16 x 4 pixels which will provide only a tiny view of stuff. Should be interesting to learn all the thermal issues first hand, i.e. stuff like keeping the microbolometer's temperature stable, doing calibrations as things warm up, the software etc etc.
The Flir E4 (as shipped) was 80 x 60 as seemed nearly "toy like". I ran it for maybe 1/2 hour before doing the software patch to run 320 x 240.
At 320 x 240 and with the lens adjusted for 2 - 3" focal distance, the E4-enhanced is an amazing tool for what I require - thermal imaging for led driver components. It can easily resolve 0603 sized smt components and individual pins of tssop ICs.
The following picture shows the 0603 sized current limit resistors heating up (the brighter yellow devices). Just to the right of the cursor in the picture is an IC package - the tiny rectangular pads you see in the thermal image are the pads protruding beyond the edge of the leadless uC package.
"visible image" of the same board. The thermal image was only of the left 2/3 of the board. For scale, those ARE 5mm LEDs on the PCB.
