Axetris IR Sources in TO-39 “Cans”


infrared_source_product_rangeItasca IL, USA & Kaegiswil, Switzerland?? –?? Axetris IR sources are micro-machined, electrically modulated thermal infrared emitters featuring true blackbody radiation characteristics, low power consumption, high emissivity and a long lifetime.

The patented design is based on a resistive heating element integrated onto a thin dielectric membrane which is suspended on a micro-machined silicon structure. The sources are packaged in compact TO-39 cans and are available with protective cap or with reflector.

They can be fitted either with Sapphire (Al2O3) or Calcium Fluoride (CaF2), or Barium Fluoride (BaF2) or Germanium (Ge) broadband filters.

Axetris IR sources are ideally suited for compact IR gas detection modules where a high emissivity, high reliability and low power consumption are key requirements.

Infrared Gas Detection Applications

  • 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, anesthetic agents, refrigerants, breath alcohols
  • Medical: Capnography, anesthesia 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
