Goniophotometer T1


The Goniophotometer T1 with device to turn the light source is a highly precise photometer for the measurement of light distributions of luminaires and lamps.

The Goniophotometer T1 allows measurements either in the C-Gamma measuring system, typical for indoor and street lighting luminaires, or in the V-H (B-ß) one, typical for floodlights: so any kind of luminaire and lamp can be considered. Some sophisticated software features allow to convert one measurement from one system to the other.

  • EN 13.032 Norm type 1.1, 1.2, and 1.3
  • Recommendation CIE n.70 Chapt.5 Type 1 and 2 (Goniophotometer with Facility for Turning the Light Source)

Maximum dimensions of the luminaires to be measured:

  • Weight: kg 20
