A Short check ( Vikipedia) shows that both InSb and PbS are good for detecting light in the infrared wavelengths ( InSb in the range 1-5 micron and PbS at 1-2.5 micron or 2-4 micron, depending on temperature).
Both Materials require cryogenic temperatures (use of Liquid nitrogen or highly cascaded peltier systems).
Maybe that's why they are not so popular with Camera manufacturers ?

Pros have been using them since the 80s at least. Very expensive, IR sensors that must be cryogenically cooled.
Plumbum Sulphide, Indium Antimonide offer far better sensitivity and range than CCD/CMOS, are on market for almost 100 years, but still, FPAs made from them only recently showed up, and only in military, guess why?

There should be some special recognition for the first guy who brings a liquid nitrogen tank to a star party!

And regarding the "pros are using since 80s", can you post a link/name/model of manufacturer/array/etc? (P.S. I know one, it's name begins with T and ends with N )
For the liquid nitrogen flask - this is quite usual accessory on Overclocker parties, see no reason why not should became typical on star parties, too.
