Radiometric software for spectroradiometers

JETI LiVal is 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
  • CIE 2017 Color Fidelity Index
  • Photobiological hazard measurements according to IES 62471
  • Color Rendition Index TM-30
  • History diagrams
  • Different observers (including CIE 2006, CIE 2015 and Judd-Vos)
  • Calculations for Museum Lighting
  • ipRGC-Influenced Responses to Light

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:

scb 1211-2

  • Radiance (Luminance)
  • Irradiance (Illuminance)
  • Radiant flux, Luminous flux (with optional integrating sphere)

scv 1501 | 1511

  • Radiance (Luminance)
  • Irradiance (Illuminance) with optional diffusor

JETI LiVal includes the following additional calculations

  • Metamerism values (ISO 23603)

  • Circadian metrics (DIN V 5031-100, June 2009 and DIN SPEC 5031-100, August 2015)

  • Photosynthetically Active Radiation (PAR)

  • LED values as dominant, peak and centroid wavelength and FWHM

  • RGB values in many different color spaces

  • Color values xy, u´v´, XYZ

  • Spectral and Ratio calculations
