Dear Kevin
I have enjoyed your experiments. I was wondering I you could get a different temperature from the mirror by trying to receive different incident angles. At some point there will be a very effective reflection off the surface of the glass, not the mirrored surface behind it.
Because glass is a pretty good absorber of IR it is also a pretty good emitter.
One thing for sure, when testing a new surface you should calibrate the emissivity using a contact thermocouple - often provided with the unit if the emissivity is adjustable. Frank has that sort.
Regards
Crispin
PS anyone see the CME impact in N America?
