Osram launches 940nm high-flux IRED with 150° beam angle

Osram Opto Semiconductors GmbH of Regensburg, Germany has launched the SFH 4726S, a high-power member of its IR Oslon Black product family with a wide beam angle of 150° (±75°) in a 3.85mm x 3.85mm package.

When integrated in reflector-based optics, the infrared LED (IRED) pre-shapes the light beam, concentrates it and can then focus it efficiently via other optics. As a result, smaller optics can be used, permitting generally more compact lighting solution designs. This system can replace the current conventional approach, which requires optics with a much larger optical aperture. Also, the smaller dimensions offer much greater design freedom for lighting solutions. Another advantage is the new IRED’s high optical performance of 990mW at a current of 1A. Radiant intensity is 215mW/sr.

Like the SFH 4725S sister IRED product, the new Oslon Black SFH 4726S has a wavelength of 940nm. This long-wave radiation at the red end of the spectrum is barely visible to the human eye. Even the slight red glow that can be perceived at a wavelength of 850nm rarely occurs with this version. Infrared LEDs are hence ideal for discreet surveillance applications, e.g. in the main hall of a bank or at border crossings.

Other application for the IR Oslon Black family include optical vehicle security systems or gesture detection for computer games.
