If we point IR camera towards the sun what we will measure? Shaibal Ghosh 7/17/2007

1) Will it show the temperature it is viewing is beyond 2000 Deg C? With a error in reading (Accepting the fact, that the camera used is calibrated to measure up to 2000 Deg C).

2) Or it depends on the embedded program of IR camera done by various manufacturers.

3) Why there is no IR camera available in the market which can measure beyond 2000 Deg C.

4) What are the limitations in fabrication of such camera?

5) What are the rules that govern the measurement temperature criteria both upper limit and lower limit in design of IR camera?

Best Regards,

For most cameras you would probably measure the failure time for the detector.

I will try to answer your questions

1. Yes, but with that high energy input you might cause permanent damage to the detector (it depends on the type of detector)
2. -
3. The IR cameras are not geared to measure that high of a temperature and there isn't a large market for this, (Accurate temperature references above 2000 C are very expensive and most customers are not prepared to cover the cost) Temperatures above 2000 deg C has most of it's energy in the Visual wavelength and therefore very inexpensive pyrometers are a better choice.
4. Market and cost.
5. same as 4
