    Default Cheap Thermopile

    I was looking for the famous Coherent Head ($$ lots even on ebay) when I ran across this thermal sensor and was wondering if painted flat black (high temp paint) could work as a thermopile based laser power meter? (Lots less expensive) Would need calibration of course; referencing to a good LPM.
