Goniophotometer

PHOTOGLOBE 4FA COMPACT

It measures the spatial distribution of the luminous intensity of luminaires, the luminous flux of light sources as well as all the colorimetric parameters.

  • Far-field goniophotometer with no mirrors
  • Fixed position of the luminaire throughout the entire photometric measurement
  • Possibility to measure luminaires in any working position
  • 100% compliant with UNI EN 13031-1and IES LM-79-08 standards
  • Fast measurement: 10 L class  sensors acquiring data simultaneously (0,01÷300.000,00 Lux)
  • PTB traceability for illuminance
  • METAS traceability for chromaticity coordinates and CCT
  • Installation and use in a small space (2,5 x 2,5 x 2,6 meters)
  • Possibility to measure luminaires with maximum weight of 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 price-quality ratio
  • Free post-selling assistance and support

Photoglobe 4FA COMPACT is a far-field goniophotometer using 10 acquisition sensors patented by Sedis Light

and the SVRG 36-83 Spectrophotometer designed and manufactured by our company.  

These technologies:

CARRY OUT

  • absolute measurements
  • relative measurements
  • flux measurements for light sources (Lumen)

VERIFY

  • color uniformity between luminaires by means of the MacAdam Ellipse   
  • stabilization of light sources

EXPORT

  • EULUMDAT (.ldt) – photometric measurement
  • UNI11733 (.Xml) – photometric measurement
  • IESNA (.ies) – photometric measurement
  • IES TM-33-18 (.Xml) – photometric measurement
  • .cvs – data returned by the spectrophotometer

RETURN

  • Spectral irradiance (µW* cm-2 * nm-1)
  • Tristimulus values X, X1, X2, Y, Z
  • Chromaticity coordinates x, y
  • Chromaticity coordinates u’, v‘
  • Correlated color temperature (CCT)
  • Chromatic difference (DC)
  • Chromatic rendering index (CRI)
  • Color components (R1, R2, …. , R14)
  • Fidelity Index
  • Gamut Index

POST-PROCESSING SOFTWARE

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

The software generates a .PDF measurement report containing, in addition to the above listed data, the following:

  • efficacy (lm/W)
  • calculation of the beam of light of luminaires
  • polar diagram
  • Cartesian diagram
  • representation of chromaticity coordinates x, y  in CIE 1931 diagram
  • representation of chromaticity coordinates u’, v’ in CIE 1976 diagram
  • graphical representation of color components
  • graphical representation of the Gamut Area
