WHY TO CHOOSE PHOTOGLOBE 4FA
Photoglobe 4FA is a far-field goniophotometer using 19 acquisition sensors patented by Sedis Light Technology
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

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
