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 
Axetris IR Sources suit medical applications including Capnography, anaesthesia gas monitoring, respiration monitoring, pulmonary function monitoring and breath alcohol measurement

EMIRS 200

EMIRS200 are packaged in compact TO-39 cans and are available with protective cap or with reflector; Sapphire, CaF2, BaF2 and Germanium windows are op-tional. Axetris IR sources are ideally suit-ed for compact gas detection modules.

IR Sources for Capnography Capnography is a non-invasive method that measures the concentration of carbon dioxide during expiration (EtCO2). Initially used in hospital surveillance and emergency care, capnography is rapidly becoming popular in medical practices and homecare medicine. The trend to miniaturize such modules emphasizes the advantages of the Axetris MEMS-based broadband infrared (IR) sources for NDIR gas detection.
