OSRAM Opto Semiconductors’ infrared (IR) Dragon SFH 4236 extends the IR DRAGON family by maximizing radiant intensity from a small form factor. The device 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 SFH 4236 IR LED achieves a typical radiant intensity of 650 mW/sr at a dc current of 1 A, which is more than three times that of the standard IR Dragon. It emits at a wavelength of 850 nanometers and is a compromise between maximum spectral sensitivity for charge-coupled device and complementary metal oxide silicon cameras and suppressed visibility for the human eye. According to the company, the total height of the SFH 4236 is about 35% smaller compared to conventional Dragon solutions with an external lens.
