OSRAM Opto Semiconductors released what it claims is the smallest infrared LED on the market with more than one watt of optical power.
The new IR OSLON SFH 4715S measures 3.75 x 3.75 mm², enabling designers to develop compact illumination units for CMOS and CCD cameras. The company said it was able to acheive this through its OSRAM's nanostack chip technology combined with a temperature-stable OSLON Black Series package. The stacked chips have two p-n junctions connected in series and generate nearly twice the optical power of conventional emitters, the company said. The OSLON Black Series package is based on a metal lead frame, and its thermal expansion exactly matches the thermal behavior of circuit boards.
The infrared OSLON typically provides 1070 mW optical power at 1 A operating current and features a typical thermal resistance of only 6.5 kW. A lens with a ±45° emission angle is integrated into the device. With this outcoupling lens, the IR OSLON delivers 15 percent more output power than components without lens, according to the company.
With a wavelength of 850 nm, the IR OSLON is well matched to the sensitivity range of CMOS and CCD camera sensors. The miniaturized package permits compact arrangements that enable a very high power density. This improved power is especially beneficial for 3D cameras since the IR-LED can be modulated up to very high operating currents of 5 A in the range of 10 MHz.
