Osram introduces 940nm IR LED with 150degree beam angle

Better beam shaping, with more compact optics


Osram Opto Semiconductors is launching the SFH 4726S, a high-power member of its IR Oslon Black product family with a wide beam angle of 150degrees. 

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 will replace the current conventional approach, which requires optics with a much larger optical aperture. Customers also stand to benefit, for the smaller dimensions offer much greater design freedom for lighting solutions. Another advantage of the new IRED is its high optical performance of 990mW at a current of 1A.

Like its sister IRED product, the SFH 4725S, the new Oslon Black 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 which can be perceived at a wavelength of 850nm rarely occurs with this version. Infrared LEDs are hence suited for discreet surveillance applications; for instance in the main hall of a bank or at border crossings.

The launch of the SFH 4726S now provides customers with another Osram product for discreet security surveillance. Other fields of application for the IR Oslon Black family include optical vehicle security systems or gesture detection for computer games.

Earlier this month, the company also announced the 850nm Oslon Black SFH 4715A (pictured above), which boasts a typical electro-optical efficiency of 48 percent.

Commenting on the  the SFH 4715A, Jörg Heerlein, senior manager for product marketing at Osram Opto Semiconductors said: "We are not aware of any other opto-electronic component with an optical efficiency to rival this one. Thanks to a boost in output to 800mW (previously 630mW) the new Osram IRED can illuminate objects over 100m away depending on the application and type of external optics. What's more, this higher output generates more light, improving the image in the process."
