IR sensors measure targets as small as .43mm (.017 in). The limitation is the temperature and emissivity. As the temperature goes lower or the emissivity is lower, then the instrument cannot go as small in spot size. The sensor will have to be placed closer to the target and a close focus lens will have to be utilized.
