The infrared Dragon SFH 4236 LED adds to the IR Dragon family by maximising radiant intensity from a small form factor.
The latest device is designed for applications that require narrow radiation characteristics from limited board space, namely motor vehicle applications such as driver and passenger monitoring systems and blind spot detection systems, as well as camera-based vision systems for the industrial and security sectors.
The company’s SFH 4232 IR LED achieves a typical radiant intensity of 650 mW/sr at a DC current of 1 A, more than three times that of the standard IR Dragon. The device emits on a wavelength of 850 nm and is said to be the best compromise between maximum spectral sensitivity for CCD and CMOS cameras and suppressed visibility for the human eye.
Designed with motor vehicle applications in mind, the total height of the 4236 is about 35% smaller compared with conventional Dragon solutions with an external lens.
The 850 nm IR Dragon family consists of the standard version SFH 4232, the stack version SFH 4235 with twice the total radiant flux and the SFH 4236 with integrated lens.
