Well not so bad even so, sounds like being (just about) usable.

The 1206 is at the larger end of the SMT scale. If I were to invest in
this for testing purposes, I'd want something that could handle the
smallest parts I'm likely to run across.

Such a device with a macro focus might work quite nicely, but I'm
unfamiliar with that end of the technology.

Would be perfect, but I am unfamiliar with IR optics either.
Slaughtering the
device and moving its lens somewhat further from the CCD might well
work, too.


I doubt you'll be 'slaughtering' one of these. I'm not familiar with the
Chinese product lines, but thermal cameras of this type start at $2K to
$3K USD (and go up).
