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 that:

SOFTWARE POST-PROCESSING
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
