IR Sources

Axetris IR sources are suited for compact IR gas detection modules where a high emissivity, high reliability and low power consumption are key requirements. Axetris IR sources are micro-machined, electrically modulated thermal infrared emitters featuring black body radiation characteristics, low power consumption, high emissivity and a long lifetime.

The EMIRS 50 is the miniature IR emitter from Axetris, with an emitting area of 0.8 x 0.8 mm2. The small size of the emitting chip, combined with an efficient design, offers excellent modulation depth; this enables gas detection system designers to choose an emitter modulation frequency to optimize the signal-to-noise (S/N) ratio required to achieve the target gas detection limit. This infrared source is ideal for portable gas sensing applications.

Infrared Gas Detection Applications in detail:

  • Measurement principles: non-dispersive infrared spectroscopy (NDIR), photoacoustic infrared spectroscopy (PAS) or attenuated-total-reflectance FTIR spectroscopy (ATR)
  • Target gases: CO, CO2, VOC, NOx, NH3, SOx, SF6, hydrocarbons, humidity, anaesthetic agents, refrigerants, breath alcohols
  • Medical: Capnography, anaesthesia gas monitoring, respiration monitoring, pulmonary function monitoring, breath alcohol measurement
  • Automotive / Transportation: Exhaust gas monitoring, breath alcohol testing (Interlock/Alcolock), demand controlled ventilation
  • HVAC: Demand controlled ventilation, refrigerant monitoring
  • Safety & Industry: Combustion gas analyzers, gas detection in fluids, incubators
