Older systems:
- Materials SIG LDEF databases from Boeing (PC version - requires Filemaker Pro) -- Ag/TFE, treated Al, and thermal paints databases available
The Boeing LDEF database is controlled by Gail Bohnhoff-Hlavacek at (206) 773-6892 and Gary Pippin, (206) 773-2846, both at Boeing.
We also use a PC program here called Therm, that will search for a material and display thermal properties in a chosen unit set.

Spectrometer info -- units used for quick, portable optical measurements at LaRC
Infrared reflectometer, Gier Dunkle DB100. This is a very old
unit bought about 10 years ago for ~$19K. It gives total normal
emissivity. Roughly, the DB100 works by irradiating a sample with alternating hot and
cold sources, and measures total energy given off, using a vacuum
thermocouple. The reflected energy alternates with the frequency of the
source changeover, and thus can be subtracted from the signal, leaving total
emissivity as the measured quantity. Accuracy is 1% for diffuse samples.
Measurement time can be as short as 3 seconds. The manual goes into more
detail.
The company (Gier Dunkle) was in California, but
may have been bought by a larger corporation out there.

Solar reflectometer, D&S Inc., MK-5. This is a solid state technology Solar Spectrum Reflectometer, model SSR-R, bought in early 1980's for ~$13K. The company, Devices and Services, is in Dallas, Texas, at http://www.devicesandservices.com/ (external link).
Both of these are reasonably portable (each box ~2' x 2' x 1', less than 40 lbs).
