All you can measure at the Planetary Emissivity Laboratory (PEL): the case of quartz 0-25 micron

Abstract

The Planetary Emissivity Laboratory (PEL) of DLR in Berlin is equipped with two FT-IR spectrometers to allow measurements from the visible to TIR range using bi-conical reflection, transmission and emission spectroscopy. The PEL has been operating in various configurations for the last 10 years. The laboratory experimental facilities consist of the main emissivity spectrometer laboratory, a supporting spectrometer laboratory for reflectance and transmission measurements, sample preparation facilities and an extensive collection of rocks and minerals. In this paper we will show and discuss the emissivity, reflectance and transmission measurements in all the possible spectral ranges and environmental conditions that we can cover at PEL on the same sample of quartz in the 0-25 µm grain size range
