Thanks to the SFH 4718A IRED, illumination units for camera systems with a medium capture range no longer require secondary optics. The Oslon Black family now offers a wide selection for the most varied of infrared-based applications, taking in four power classes with optical outputs ranging from 0.3W right through to 2W , three wavelengths (810nm, 850nm and 940nm) and three beam angles (±25°, ±45° and ±75°). Key applications include the illumination of areas monitored by closed-circuit television (CCTV) systems using infrared light. CCTV is used, for instance, to monitor public spaces, parking lots and company premises, as well as museums and bank foyers. Adding infrared illumination ensures that the camera delivers high-quality images regardless of the prevailing light conditions. The IRED can also be used for automatic license plate recognition systems. At a current of 1 amp, the IRED offers an optical output of 0.8 watts. Their 850nm wavelength is barely discernible by humans, but lies firmly within the sensitivity range of the camera sensors.
