The Planetary Emissivity Laboratory (PEL) is a special sub-session of the Planetary Spectroscopy Laboratory (PSL) of the DLR in Berlin, devoted to emissivity measurements in of samples from low/moderate to high temperature (temperature range from 300 to above 1000 Kelvin).
Emissivity measurements are recorded by using an external emissivity chamber (DLR-custom-designed) attached to a Bruker Vertex80V FTIR from the visible to the far-IR (from 0.4 to 150 µm), with a high SNR. Induction system …

The Planetary Spectroscopy Laboratory (PSL) provides spectral measurements from VIS to FIR for comparison with remote sensing spacecraft/telescopic measurements of extraterrestrial surfaces. Reflection, transmission and emission spectroscopy are used to acquire spectral data of target materials.
An FT-IR microscope allows microscopic analysis in transmission and reflectance in the VIS+VNIR+MIR spectral range. Three identical Bruker Vertex 80V FTIR instruments are operating (in vacuum) at …
