I am looking for a way to optically measure temperatures in a very small space. I have looked at the so-called IRt/c's and everything I have seen is to large. I have a gap of about 1mm I need to insert something into. Just to keep it interesting, I need to "look" at a 90 deg angle to the direction of insertion. In other words, I need to look at the wall of the channel I am inserting the sensor into. I thought maybe there was a device that would use a fiberoptic fiber to transfer the light back to an IR sensor, but so far I haven't found it. Any suggestions?
