Depending on the type of camera and number of infrared light emitting diodes, the SFH 471xAS can provide illumination over a distance of more than 328 feet (100 meters), which make them ideal IR light sources for many camera-based applications.
The IREDs come in a small 3.85 mm2 package with an integrated lens that allows superior compact arrangements of very high power density. The LEDs have a low thermal resistance of 9 K/W (max), a centroid wavelength of 850nm and a typical optical power that reaches 1.34 W with 42 percent efficiency at 1A.
With beam angles of 90 degrees (SFH 4715AS) or 150 degrees (SFH 4715AS) and reduced cooling requirements, the LEDs efficiently deliver high output power while requiring fewer components, saving cost and board space.
With their extended output and range, the SFH 471xAS IREDs provide efficient infrared light for surveilance, gesture recognition and machine vision systems.
