We frequently see projects based on IREDs for detection and measurement.

I cannot find any non-subscription source with near infrared spectra of common substances, like water, purified mineral oil (Nujol), and vegetable oil (say, olive oil). Some of the modern plastics, such as acrylics, acetates, and polycarbonate would also be helpful. The only reference I did find was some 1920's work at 900 nm with water.

Can anyone provide a link to such information in the range from 700 to 1200 nm, particularly 940 nm?

Hello John,

Perhaps you can find something on this site:
http://www.spectroscopynow.com/coi/cda/home.cda;jsessionid=C744FAD165E6E9BA3AA8FF5210405F F6?chId=2

Attached there is a file from one of the companies I work for.
It contains a some IR tables.

Greetings,
Bertus

Thank you , Bertus. Extremely useful, as usual. Near IR was just not part of my studies when I was in school.

What about the van halen effect and space flights.
