IRED output provides illumination to 100 m

The SFH 4715AS and SFH 4716AS infrared light emitting diodes (IREDs) feature increased output for the second time in six months and are the the company’s most powerful IREDs. This has been achieved by combining the latest chip design with an optimized package and nanostack technology, in which each chip has two emission centers. Depending on the type of external optics and the particular application, the IREDs provide illumination over a distance of more than 100 m, making them light sources for many camera-based applications.

The IREDs provide 1.37 W optical output at 1 A. The devices are the preferred light sources for surveillance cameras. In addition to their use in surveillance cameras, the IREDs are also suitable for 3D process control cameras to determine the distance from an object by measuring the propagation time. The package dimensions remain unchanged at 3.85 x 3.85 x 2.29-mm or 1.51 mm. They also offer a choice between beam angles of 90 and 150 degrees.
