Super low-profile IRED permits eye tracking in mobile devices


OSRAM OPTO SFH 4770S compact Synios infrared LED (IRED) in a high-power class provides low profile and high optical output of 1200mW and broad emission characteristics. Package measures 2.7mm x 2.0mm x 0.6mm and provides optimum light extraction. Installed in the IRED is a 1 mm2 emitter chip with a wavelength of 850 nanometers (nm) in which two emission centers are provided with the aid of nanostack technology, in which two emission centers are epitaxially stacked in one chip. Overall, the component delivers a typical optical output of 1200mW at a current of 1 ampere (A) with only one chip. The emission angle of 120° ensures that the target area is evenly illuminated.  http://www.osram-os.com
