  * **ASD FieldSpec 3 spectrometer** covering the 0.4-2.5 µm domain ([[https://www.asdi.com/|ASD Inc.]]).
  * **ISEP** (Imageur Spectral pour l’Exploration Planétaire) is a dedicated laboratory wide field spectrophotogoniometric imaging facility set up at [[http://www.irap.omp.eu/en|IRAP]], Midi-Pyrénées Observatory, Toulouse, France ([[https://www.lpi.usra.edu/meetings/lpsc2001/pdf/1552.pdf|Pinet et al., 2001]], [[http://www.sciencedirect.com/science/article/pii/S0019103503002045|Cord et al., 2003]], [[http://www.sciencedirect.com/science/article/pii/S0019103511002405|Souchon et al., 2011]]). \\ This instrument covers the 0.4-1.0 µm domain and operates under either natural solar or artificial extended light source and characterizes the optical response of geological targets from 10 mm x 10mm to 20 cm x 20 cm size, ranging from controlled powders to complex slab rock samples.
