Osram Opto Semiconductors reports that it is adding the SFH 4718A IRED to proven Oslon Black portfolio. The SFH 4718A IRED features a narrower beam angle of ± 25° than the company’s previous IR LEDs. The company insists that with the new IR LED, secondary optics will no longer be required for illuminating mid-range camera systems.
With the addition of the SFH 4718A, the Osram Opto Semiconductor’s Oslon Black family now offers infrared-based options that include three wavelengths (810 nm, 850 nm and 940 nm) and three beam angles (±25°, ±45° and ±75°). Also, the company offers four different power levels with optical outputs from 0.3 W to 2 W. And like all other Oslon Black they are based upon the same package and an identical footprint, making the emitters easy to combine or upgrade with a new variant.
“We’re excited to introduce the SFH 4718A IRED, providing the perfect illumination solution for mid-range CCTV and home security systems,” said Eric Kuerzel, product marketing manager at Osram Opto Semiconductors. “Our Oslon Black family continues to expand and deliver compact illumination offerings that are specifically designed to meet the needs of the market at a competitive price.”
Additional Secondary Optics Not Required for Mid-Range Cameras
For mid-range camera systems, this light source can be embedded without additional secondary optics, thereby making the overall system more compact and cost-effective.
The SFH 4718A also boasts a radiant intensity of 730 W/sr, and at a current of 1 amp, and the IR LED delivers an optical output of 0.8 watts (W). Although the 850 nm wavelength is barely discernible by the human eye, it lies firmly within the sensitivity range of a camera’s sensors.
Also, the company points out that its Oslon Black series spans all types of infrared illumination. Primary applications include the illumination of areas monitored by closed-circuit television (CCTV) systems and using infrared light to monitor homes, public spaces, parking lots and company premises, as well as bank lobbies and museums.
Osram Opto Semiconductors contends that adding infrared illumination ensures that the camera provides high-quality images regardless of the prevailing light conditions. Another potential application for the IR LED is for automatic license plate recognition systems.
