The new 1 mm2 infrared chip prototype from Osram Opto Semiconductors (Sunnyvale, CA) has achieved an efficiency of up to 72 percent at 100 milliamps using thin-film technology. The wavelength of the chip prototype is perfect for infrared illumination, particularly for surveillance tasks and use with CCTV cameras. Features include:

  • An operating current of 1 amp.
  • A wavelength of 850 nanometers.
  • A specific infrared illumination application design.
  • A high quantum efficiency that remains around 65 percent up to 1 amp.
