ICCS – Illuminance Color Check System

Equipped with Spectrophotometric Sensor

It is the right instrument to perform a very quick check of the luminous intensity distribution of a luminaire.

ICCS with spectrophotometric sensor allows to perform photometric measurements as well as to measure/calculate the spectral data and the colorimetric parameters of luminaires/light sources.

  • Composed by a luminaire support operated by a stepper motor, which makes the luminaire rotate +/-180° around its first axis (polar axis)
  • Equipped with an acquisition sensor, which remains fixed throughout the entire photometric measurement
  • L class  sensor acquiring data in the range 0,01÷300.000,00 Lux
  • PTB traceability for illuminance
  • METAS traceability for chromaticity coordinates and CTT
  • 100% compliant with UNI EN 13031-1 standard
  • Aluminum structure composed by two supports that can be easily positioned
  • Possibility to measure luminaires with maximum weight 30 kg
  • Possibility to measure luminaires with maximum dimensions of 1,0 meter
  • Easy positioning of the luminaire 
  • Easy luminaire testing for design purposes
  • Excellent quality-price ratio
  • Free post-selling assistance and support


  • The SVRG 36-83 Spectrophotometric sensor can be easily removed and used as portable device
  • ICCS equipped with Spectrophotometric sensor calculates/measures spectral data and colorimetric parameters both along the second axis of luminaires, in one point, and as spatially averaged values.

ICCS – Illuminance Color Check System is a gonio-spectroradiometer that:


  • absolute measurements
  • relative measurements
  • luminous flux measurements


  • chromatic uniformity through the MacAdam Ellipse


  • EULUMDAT (.ldt) – photometric measurement
  • UNI11733 (.Xml) – photometric measurement
  • IESNA (.ies) – photometric measurement
  • IES TM-33-18 (.Xml) – misura fotometrica
  • .cvs – spectral data


  • spectral irradiance (µW* cm-2 * nm-1)
  • tristimulus values X, X1, X2, Y and Z
  • chromaticity coordinates x, y
  • chromaticity coordinates u’, v’
  • correlated color temperature (CCT in °K)
  • chromatic difference (DC)
  • chromatic rendering index (CRI)
  • Color components (R1, R2, …, R14)
  • Fidelity Index
  • Gamut Index


Measurement data are processed by a powerful post-processing software.

The colorimetric parameters are exported in text format (.cvs ) and they can be subsequently imported in the measurement report.

By importing the .ldt/.ies files and/or the spectral data, the software generates a PDF report containing information, graphical representations and calculations which are not envisaged in the .ldt e .ies standard formats, and they are:

  • laboratory environmental conditions (temperature, humidity, air movement);  
  • the reference standard referring to the type of measurement performed;
  • the photo of the luminaire under measurement;
  • the opening angle of the lighting fixture;
  • the representation of the light emission not only in polar coordinates but also in Cartesian coordinates
  • the efficiency calculations of the LED module, of the lighting system and of the luminaire ( lm/W);
  • the spectral irradiance both in table and graphical form;
  • the colorimetric parameters in table form;
  • the graphical representation of the CIE 1931/CIE 1976 diagrams of the chromaticity x, y /u’, v’;
  • the graphical representation of the necessary color components for the calculation of the CRI;
  • the graphical representation of the Gamut Area;
  • and more…
