INFRARED ASSOCIATES DETECTOR INFO NEEDED

[Richard W. Solomon, W1KSZ]

I acquired an Infrared Detector in a lot but cannot locate any info
on it. It was made by Infrared Asscociates of New Brunswick, NJ,
and the label says Model Number HCT-NB-A.

Does anyone have any info on this ? I hate to trash it if it can be
used by someone.

Thanks, Dick, W1KSZ

Awfully decent of you to make mention of my previous posts.
I still have some of it available.

Now my question is, who died and left you in charge ??

73, Dick, W1KSZ

If you pulled the same kind of crap in meatspace that you pull on
Usenet
(e.g. walk into a conference room and launch into an Amway spiel)
at best, I would expect you to be escorted out of the room roughly.
If you pulled this crap in some places I know of,
you would come out of the experience beaten and bloody.

Groups that welcome advertisements ARE NOT HARD TO SPOT.
In their names they have words like ads biz forsale marketplace

I don't recognize the model number, but my experience with them had
been that they are photoresistors.. With a constant bias of a few volts,
mre trickle current flows when there is light ot IR falling on them. The
sesitive spot was located at the focal point of a refracting lens (that
transmits in the infrared) or a small parabolic mirror. They often had
to be cooled. If it is of a cooler type, the senstitive spot was under
the bottom of a contaner.. looks like a small inkwell.

drmant resistance was a few hunderd k at room temperature; few megs
when cooled.

Does anyone have any info on this ? I hate to trash it if it can be
used by someone.

Mu last crack at them was inthe 1950's.
