- Analysis
- To calibrate the absolute reflectance of our measurement, we acquired reference spectra in the vacuum chamber using a Spectralon standard (99% Lambertian reflectance, Labsphere). An additional reference measurement was performed on InfraGold (Labsphere), which allowed the correction of minor NIR features present in the Spectralon spectrum.
