I just secured a vintage IR camera.
It will make a nice display item for this subject.
In today’s money, it would cost about $250,000 to buy. Back then, they had to pay around $8K per year
to maintain the camera and replace the liquid nitrogen every month. The life expectancy of the unit was
about 5 years.

Cool.
I hope you took a TI class first. lol
Interesting note… the IR detectors in this camera had to be kept below -360 degrees in order to keep working. That is what the liquid nitrogen was for.

Very cool
Brings back memories, I ran one of those for almost two years it was way older than 5 years old , It had a swappable zoom lense for shooting power sub stations, also the nitrogen was cheap, and fun to play with.
Nice
