Based on Nanostack technology, in which each chip has two emission centers, IR Oslon Black SFH 4715AS and SFH 4716AS can provide illumination over distance of more than 109.36 yards. Units deliver optical output of 1.37 W at 1 A and offer choice of 90 or 150° beam angles. Measuring 3.85 x 3.85 x 2.29 or 1.15 mm, IREDs are used in surveillance cameras as well as 3D process control cameras to determine distance from object by measuring propagation time.
