Number of spectra
58
Variable type(s)
  • irradiation dose
Comments
The reflectance spectra were averaged from the Region Of Interest (ROI) selected from the hyperspectral cube of the sample, as its water sublimates with time.
Instrument
Hyperspectral imaging system Vis-NIR
Sample holder
Aluminum sample holder, rectangular 120x60 mm with a thickness of 20mm, equipped with PT100 temperature sensors
Standard medium
air

Spectral range type(s)
Vis, NIR
Valid spectral range(s)
Min - Max (${\mu}m$) Sampling (${\mu}m$) Resolution (${\mu}m$) Position accuracy (${\mu}m$) Absorption edge
#1 0.38 - 0.96 0.02 0.015
#2 0.96 - 2.3 0.01 0.03
Observation geometry
biconical
Observation mode
fixed angles
Emergence angle
13.0°
Azimuth angle
0.0°
Comments
The light beam emitted from the extremity of the fibre bundle positionned about 300 mm above the sample surface has a divergence half-angle of 12.7°. The light source incidence and azimuth angles are slightly variable from pixel to pixel.
Observation mode
roi averaged
Comments
Note to the provider: Complete the "image" observation_mode when fully implemented in SSHADE. Because SCITEAS data are hyperspectral images.
