Expert knowledge for different optoelectronic devices such as LEDs, laser diodes, image sensors, fiber optic devices and entire optical systems.

Optoelectronic services include:

• selection of LEDs resp. definition of chromaticity coordinate:
  parameter like XY-coordinate, dominant and peak wavelength, spectral curve

• life test an burn-in of LEDs and laser diodes with online-measurement
• check of heat allocation and heat dissipation
• radiation characteristics (check of data sheet)
• eye safety measurement for LEDs/ classification
• risk assessment of new technologies

Failure Analysis on LEDs:

• visual inspection to detect mechanical faults, corrosion or contamination
• measuring of various optoelectric and electric parameters like spectrum, radiant characteristics, leakage current, thermal resistance
• SAM (scanning acoustic microscopy), X-ray and X-sectioning to detect cracks and delaminations/ check of solder joints and bond connections
• special preparation and failure analysis on chip level (cristal structure)

Approval and analyses for various applications like aerospace, general lighting, industry electronics, medical equipment and automotive.
