Min - Max (${\mu}m$) Sampling (${\mu}m$) Resolution (${\mu}m$) Position accuracy (${\mu}m$) Absorption edge #1 2.0 - 25.0 - Comments
- The MIR reflection measurements were performed at room temperature only (without cryostat).
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).
