    3.3 M EASUREMENT Select a type of measurement under Measure menu (Fig. 6). Three options exist: Scope is spectrum intensity profile quantified as Irradiance [µW.cm ] or Photon flux density [µmol.m ] Light intensity is total intensity value in a spectrum range defined in the Options settings. Chromaticity diagram is light color and correlated color temperature (CCT).
