OSRAM Opto Semiconductors’ (Sunnyvale, CA) new infrared DRAGON SFH 4236 LED achieves a typical radiant intensity of 650 mW/sr at a DC current of 1A, more than three times that of the standard IR DRAGON. The device emits at a wavelength of 850nm. The new infrared DRAGON is designed for applications that require narrow radiation characteristics from limited board space, namely automotive applications such as driver and passenger monitoring systems and blind spot detection systems. The 850nm IR DRAGON family consists of the standard version SFH 4232, the stack version SFH 4235 with twice the total radiant flux, and the new SFH 4236 with integrated lens.
