Axetris EMIRS50 infrared sources are optimized for miniaturized sensor technology. Like non-dispersive infrared (NDIR) sensors, photoacoustic spectroscopy (PAS) or attenuated total reflection (ATR) spectroscopy. The sources are particularly well-suited to size-optimized and battery-powered sensor solutions in medicine as well as in numerous environmental and industrial applications. Thanks to the low thermal mass of the chip, modulation frequencies of 100 Hz are guaranteed, allowing high sampling rates.
