IR Cameras
InGaAs 0.9 - 1.7 um
InSb 2.2 - 4.6 um Very sensitive butdown at long wavelength
HgCdTe 2 - 5 um
PtSi 1 - 5 um Often sold with 3 um long pass filter
$ 25k gets you B&W system, no temperature scale
$ 60k gets color scaling, temperature readout, flash card image storage
All Focal Plane Arrays
None are gated
Many come with on-board processors, flash cards, hand held, battery powered.
Some have RS232 or 488 port.
Typical sensitivity to < 0.1oC change at source (corresp. to 2 uW/cm2 emission at source)
Typical floor is - 10o C (200 uW/cm2 at source)
They come cooled by LN, Stirling engine, TE
