To develop high-efficiency OLED devices, the improvement of light extraction efficiency is recognized as the important parameter, and researchers have been aware of the importance to control and to evaluate the molecular orientation of OLED devices. The C14234-11 is functional for measuring fluorescence spectrum with multichannel analyzer PMA-12 and for angle dependency of p-polarized fluorescence with a newly designed optics.


  • Measurement of angle dependency of PL intensity
  • Comparison to the simulation results is possible
  • Easy alignment of the optics and easy Measurement
  • Selectable excitation wavelength of LED light source unit (Options)
  • Integrated shutter to prevent the material degradation
