Luminous Flux Measurement System

Integrating sphere with spectroradiometer is to measure optical property of general light source. Depending on type of light source, the measurement configuration is different. Addison based socket used for incandescent light sources or TEC module can be installed at the center of the sphere to apply different junction temperature condition for LED-based light sources.

The available measurement parameters are:

  • Optical power vs. wavelength plot
  • Luminous flux (lm)
  • CIE chromaticity coordinates
  • Color correlated temperature (K)
  • Dominant wavelength (nm)
  • Peak wavelength (nm)
  • CRI
