 REFLET measuring system: detail
  • High dynamic range (1:109),
  • The measuring arm of this instrument comprises a (Θ,φ) goniometer.
    This architecture offers signifiant advantages over static measuring systems:
    • Real brdf/btdf measurement: no need for calibration on Spectralon.
    • Full hemisphere measurement (2π sr).
    • High angular resolution (0.1 deg).

  • Spectral and Integrated-flux modes,
  • Crossed polarizers option,
  • 6-position filter wheel option,
  • Portable Instrument,
  • Operates in ambient light conditions.
