The PEL provide the planetary community already today with emissivity measurements highly complementary to existing spectral databases. With the recently completed upgrade the PEL allows unique measurements with a strong focus on airless bodies and extreme conditions as the ones BepiColombo and MESSENGER will encounter at Mercury, over the ex-tremely wide spectral range from 1-100 μm for fine grained samples. Two accessories permit complemen-tary measurements of reflectance and transmission in the same large spectral range, that can be easily ex-tended to until 300 µm. A second instrument is used to measure emissivity at low/moderate temperatures, and bi-directional reflectance spectra at room temperature of samples, under purged air conditions. |
