Radiometric Software

JETI LiVal (included in delivery of all spectroradiometers)

The actual version of the software JETI LiVal provides more flexibility due to its new customizable interface. All measured and calculated values can be displayed as widgets and they can be arranged freely according to user's wishes. New calculations and charts are implemented such as:
  • Color Rendering Index (CRI): column and circle charts
  • Color Quality Scale (CQS): column and CIELAB charts
  • Television Lighting Consistency Index (TLCI): table and EBU R137 report
  • Color Rendition Index TM-30
  • History diagrams
  • Different observers (including CIE 2006, CIE 2015 and Judd-Vos)

Other features are the spectra export to Zemax, the application of spectral weighting functions, pass/ fail settings and the binning possibility. Data can be exported into reference files or as Excel or csv files.

The following basic measuring values can be obtained by the different models:
