Description: The system allows to determine absolute OLED efficiencies (EQE in %, Luminous efficacy in lm/W) in a single measurement. It enables recording integrated emission spectra and integrated emission colors in dependency of the applied current via SMU.


  • 300-1000nm for excitation and emission measurement
  • Electrical connection possible
