Measurement Capabilities

One of the most important aspects of a lighting system is the performance in terms of the amount of light that is emitted from the light source and picked up by the receiver. 

In the team we have the possibility to measure many of these characteristics with an appropriate accuracy, including:
  1. Luminance
  2. Luminous flux [lumen]
    Measurement of the total luminous flux provides the  total amount of useful light for lighting from your luminaire or lamp in the unit of lumen. This measurement is also the basis of the luminous efficacy (lm/W) which is used to evaluate the energy efficiency of the light. The measurements is done under  controlled conditions according to the standard CIE S 025 and LM-79
  3. Radiant flux, spectral [W]
  4. Irradiance (SP)
  5. Illuminance
  6. Luminous intensity
  7. Transmission (Direct, Spectral)
    The spectral transmittance is the ratio of the transmitted spectral radiant flux to the incident flux in the given conditions. We provide measurements of spectral transmittance of materials for light passing directly through (regular transmittance), (diffusely transmitted light is not measured) using an Agilent, Cary 50, spectrophotometer with a wavelength range of 190 to 1100 nm.
  8. Reflection (Diffuse and specular)
  9. Luminance distribution (Ray file)
  10. Intensity distribution

Measurement of light intensity, gives you the information of where the light goes from your luminaire or lamp, we provide the data in the popular formats .ies or .ldt (EULUMDAT) that can be used in simulation softwares such as dialux, rhino etc.
