Raman spectra of some sulfate minerals | REAP

Definition: incidence and emergence angles are positive with origin at nadir, and vary in same direction. Azimuth origin (increasing clockwise) is for i = e (opposition geometry).

Observation geometry: directional-conical
Observation mode: fixed angles

Spatial parameters

Observation mode: single spot
Objective type: x100
Spatial resolution: 1.0 ${\mu}m$
Comments: spot of 1 µm in diameter
