810 nm IR LED targets automated license plate recognition

March 21, 2017 // By Julien Happich
Osram Opto Semiconductors is expanding its offering of high-power infrared LEDs for illumination solutions to include a new wavelength (810 nm) particularly suited to camera systems used to read license plates.

The additional wavelength is said to improve image contrast, making it easier to read patterns from recorded images. Because camera sensors have a higher sensitivity at 810nm, for the same optical output, the SFH 4703AS extends the range of these camera systems as compared to 850nm.

Part of the Oslon product family, the SFH 4703AS outputs 1 watt of optical power at 1 amp. Its +-45° beam angle allows for a broad illumination, with a resulting radiant intensity of 630 milliwatts per steradian (mW/sr) at 1A. The device is only 3.85x3.85x2.29mm, including the lens.
