The Oslon P1616 SFH 4737 from Osram measures 1.6 × 1.6 × 0.9 mm, and is only half the size of the previous smallest product in the Osram portfolio. This compact design makes it suitable for use in smartphones, as well as its output of 74 mW at 350 mA, which is about three times the peak values of earlier solutions. It also has radiant intensity in the forward direction at 18 mW sr–1, which doubles the values of former Osram NIREDs. Its wavelength range is 650–1050 nm. The sensitivity of legacy silicon-based detectors usually decreases with increasing wavelength, especially above 950 nm. In the past, in order to compensate for this, higher currents were required. Thanks to a new phosphor, the component emits more light at higher wavelengths—with positive effects on the overall energy consumption of the system.
