The Alpha line is equipped with the frc‘3 photometer for luminous intensity measurements. Measurements of the luminous intensity distribution are conducted step by step with the desired measurement resolution. A typical measurement takes approximately 100 minutes.

Detector: Standard photometer frc-f
The Pro line uses a high-quality and very fast Class L photometer. The high precision luminous intensity distribution of a light source or luminaire can be measured in minutes.

Detector: very fast Class L photometer
The Top line combines the fast Class L photometer with a spectrometer. Luminous intensity distribution and spectral distribution with an angle (color over angle) can be measured easily and directly within minutes.

Automotive:  In the automotive industry photometric measurements need to be executed with high angular resolution in order to comply with the strict industry standards, and of course, results need to be performed and delivered extremely quickly. The robogonio’s very fast Class L photometer reduces the measurement time to just a few minutes. Furthermore the robogonio allows angular resolutions of 0.01.


Luminaires: The robogonio is perfectly suited for companies constantly launching new luminaires by quickly generating the required LED data and providing far field data (IES or EULUMDAT format). The robogonio can also be equipped with an optional spectrometer for color vs angle measurements. Furthermore Luminous flux efficiency vs consumed electrical power can also be determined directly to understand energy efficiency classification.


Signal Lights: Luminous intensity distribution is a critical metric for measuring traffic lights, railway signals, beacons etc. for production lines. Some applications require that front and back exit windows emit the same intensity, the robogonio’s flexibility makes it straightforward to model the distribution in both directions in a single setup for fast, efficient, and accurate data.
