Another inexpensive alternative is the SEEk thermal camera attachement for smart phones. At $300, with a reasonable image and easy-to-use App, it is a great alternative to more expensive thermal cameras. 
One drawback is that it does not have a mechansm to compensate for emissivity, so the temperatures will not be quantitative (although it does show an estimated temperature). If you need accurate temperatures, use the thermocouple method, if you want spatial resolution, use the camera.

One significantly cheaper solution, depending on the resolution you would need, would be to setup an array of thermopiles with narrow apertures. There is a great paper on this from NASA: http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20050061012.pdf 

Thermopiles are $2 - $4 each and you could integrate them into your system for longitudinal monitoring.

Dear All, 

To test the performance of our microscope incubators (how homogenously the heat is distributed) and for some other similar tasks (where we would like to check the spatial heat distribution) we are thinking of purchasing an IR (thermal) camera system. I was wondering if anyone on the list had experience with these system and if you could make any suggestions? We are heading for something more precise then the systems that can be attached to a smart phone, but remarks are welcome. I would appreciate any feedback. 

Thanks Gabor
