Calcite
Practical significance
Calcite is considered to be particularly important for its link with climate evolution and water resources on Mars. Moreover, calcite is also found in the Earth's atmosphere.

Refractive index
Calcite is a uni-axial birefringent material, so it has one optic axis and, instead of one refractive index, it has a dielectric tensor specified by two principal dielectric functions, the ordinary (mo) and the extraordinary (me) refractive indices. At 647 nm no=1.655 and ne=1.485. The imaginary part is assumed to be zero (Gosh 1999).
