Ushio has commenced production of its latest high-powered short-wavelength infrared (SWIR) LEDs, the Epitex D-Series. Following the prior success of the S-Series, the Epitex DSeries achieves the world’s highest output power and efficiency. Low-power chips are mounted in SMT packages and moulded type LEDs; while with 1 mm2 high-powered chips, the SWIR D-Series can be mounted in EDC, SMBB, and TO-66 packages. For the majority of wavelengths, a two-fold improvement of output and efficiency is attained; however, the high-power versions have ramped up their forward current to 1 A and gain a boost of up to four times the original radiated power output. The resulting efficiency improvement gives operators the opportunity to enjoy cheaper power output, thereby reducing the overall cost per Watt.
