Near infrared spectra

Does anyone have (or have references to) Near IR spectra of
pigments?

The region I am interested in is 700-900 nanometers, and the
materials I am most urgently interested in are Lapis Lazuli, Indigo,
Azurite and Smalt.

Alternatively, has anyone got an instrument I could use to produce
them? Thanks,
