Overview

Phelos is an angular luminescence spectrometer to characterize both OLED and other light emitting devices as well as luminescence of thin films. While traditional goniometric instruments focus on either electroluminescence (EL) or photoluminescence (PL) measurements, Phelos incorporates both techniques in one instrument and links to the powerful simulation software Setfos for parameter extraction.

  • OLED efficiency
  • Viewing angle
  • Emitter orientation and position
  • One click operation
