Databases of Laboratory Measurements
A database maintained by a Brazilian group that contains optical constants of
different type of ices: pure, mixed and energetically processed by cosmic ray
analogues in the laboratory.

- visible-6 microns and also Raman, with the sample enclosed within a cell, so
can explore solid, liquid, vapor phase equilibrium, for temperatures down to 30
K and pressures up to ~3 bar. The samples are thick, usually 5 or 20 mm that
give a good sensitivity for the very weak near-IR features in transmission, but
limited ability to study stronger absorptions. More limited vapor-deposited
thin film capability down to 7 K and out to about 20 microns.
- Reference & DataBase of Optical Constants
- Stony Brook University Vibrational Spectroscopy Laboratory; working to
determine the optical constants (n and k) of many minerals at various
orientations. For uniaxial minerals, determine n and k for the O and E rays.
For other minerals, determine the three principal complex refractive indices.
Determine n and k by acquiring mid-IR emissivity or reflectance spectra and
applying dispersion theory to generate optical constants that provide best-fit
models to the measured spectra.

- Granada-Amsterdam Light-Scattering Database; light scattering measurements of
particles (scattering matrix, angular and wavelength dependence).
- RELAB; KECK/NASA REFLECTANCE EXPERIMENT LABORATORY. Spectroscopic data
acquired in the laboratory provide the interpretive foundation upon which
compositional information about unexplored or unsampled planetary surfaces is
derived from remotely obtained reflectance spectra.
