Description
Vis-NIR spectra of Allende meteorite pellet, before and after ion irradiation at different doses.
Variable(s)
irradiation dose
Number of spectra
5
Instrument
Maya2000 Pro (Ocean Optics)
Sample holder
The sample is mounted on a vertical holder in the vacuum chamber of INGMAR setup (IrradiatioN de Glaces et Météorites Analysées par Réflectance VIS-IR, IAS-CSNSM/Orsay)
Standard medium
vacuum
Spectral range type(s)
Vis
Valid spectral range(s)
Min - Max (${\mu}m$) Sampling (${\mu}m$) Resolution (${\mu}m$) Position accuracy (${\mu}m$) Absorption edge
#1 0.36041 - 1.05974 0.0005 1.0
Incidence angle(s)
15.0°
Emergence angle(s)
15.0°
Observation mode
single spot
Spatial resolution
3000.0 ${\pm}$ 1000.0 ${\mu}m$
Comments
The collecting spot size is 3–4 mm, larger than the pellet heterogeneity, and thus representative of all constituents of the meteorite (matrix and chondrules).
