 Osram Opto 1mm2 infrared chip

Osram Opto Semiconductors had announced that its 1mm2 infrared chip prototype, which uses thin-film technology, boasts of an efficiency of 72% at 100mA. It also achieved 25 per cent higher light output than other available solutions when under lab conditions of 930mW with operating current of 1A.

The prototype IR chip has a high quantum efficiency that remains at approximately 65% up to 1A. The 850nm wavelength is ideal for infrared illumination, such as surveillance and CCTV camera applications. Potential safety uses include automotive pre-crash sensors and night vision illumination systems. The chip is expected to be in production in mid-2013
