[Milsurplus] Infrared Image Tube

[Rob Flory]

The 1946 RCA Review Reprint describes more specifically the earlier 1P25
infrared image tube as used in the WWII-era apparatus.  The 6032 is a more
refined version of the same technology with better resolution and
sensitivity, running on 20,000V versus about 3-4000 for the 1P25.

Earthlink ate my website about this stuff so it is harder to get to these
days.  You have to go through the Wayback Machine.

I recently busted out all my IR gear and checked what was and was not
working so I could show it to a kid who was working for me who is studying
physics and engineering. Somewhat predictably out of a basement that was
humid for a while, most of the rectifier-based gear worked, and none of the
vibrator-based gear did.  The vibrators in the US/C-3 telescopes are not in
sealed cans like many of the era, both a blessing and a curse.  The curse
being they get exposed to humidity, the blessing being the rubber in the
can doesn't mess them up and the points are easy to clean.
