Measurement Engineering

Our photometric and radiometric laboratory is well equipped with calibrated optical instruments to measure the electro-optic parameters of single LEDs, LED modules and photodiodes. We can accurately determine radiation pattern (viewing angle) for LEDs and reception characteristics of photodiodes. We measure parameters in visible spectral region:

  • luminous intensity
  • luminous flux
  • peak, centroid or dominant wavelength
  • colour coordinates (in compliance to CIE standards)

and additional in in ultraviolet and infrared:

  • radiant intensity and radiant flux (radiant power)

Degradation measurements and burn-in are performed with special test benches at different forward DC and pulse currents.

We are looking forward to test also your LEDs and photodiodes. Please contact us to discuss your request!
