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.
