Axetris Ag

- Model EMIRS 200 - Customized Infrared Sources for Gas Detection and Monitoring



Axetris IR sources are micro-machined, electrically modulated thermal infrared emitters featuring true black body 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, CaF2 or BaF2 or Germanium windows.

Axetris IR sources are ideally suited for compact IR gas detection modules like non-dispersive infrared spectroscopy (NDIR), photoacoustic infrared spectroscopy (PAS) and attenuated-total-reflectance FTIR spectroscopy (ATR).

Because of the broadband emission, Axetris IR sources can be used for all IR-active Target gases such as CO, CO2, VOC, NOx, NH3, SOx, SF6, hy-drocarbons, humidity, anesthetic agents, refrigerants, breath alcohols.

  • True black body radiation (2 to 14 μm)
  • High emissivity
  • Fast electrical modulation (no chopper wheel needed)
  • High modulation depth
  • High electrical input to optical output efficiency
  • Low power consumption
  • Long lifetime
  • Rugged MEMS design (passed the requirements of IEC 60721-3-7 Class 7M3, except for BaF2 and CaF2 windows)
