Luminous intensity
distribution
Determination of the luminous intensity distribution of
a light source or fixture (.ldt/.ies file) in one of our 3 stateof-the-art near-field goniophotometers.
Flux determination
Determination of the radiant flux (W), luminous flux (lm),
luminous efficacy (lm/W) in an integrating sphere or
near-field goniophotometer setup, depending on the size
of the source. The electrical parameters (voltage, current,
power, power factor) can be determined as well.
• Measurements and analysis according to
the relevant standards
• Object diameter up to 2m
• Glare rating (Soellner and UGR)
• Spectral characteristics (colour coordinates,
CRI and CCT)
• Generation of ray files in various formats (ASAP,
LightTools, Zemax, TracePro, ...)
Optical material
characterisation
• Reflection and transmission properties
• Spectral and spatial Bidirectional Scatter
Distribution Function (BSDF)
• Gloss properties (specular gloss measurement,
distinctness of image)
• Absolute luminance and chromaticity measurements

Spectral distribution
Colour coordinates (x, y, z)
Correlated colour temperature (CCT)
Colour rendering index (CRI)
Can be measured both in the near-field goniophotometers and in the integrating sphere.
With our measurement
equipment, a whole set
of input parameters can be
determined for accurate
computer simulations
(ray tracing software),
allowing a complete optical
simulation of your luminaire.
