All Axetris IR sources are micro-machined thermal infrared emitters. The patented design provides a true black body radiation characteristic from 2 to 14 μm, high emissivity and a long lifetime. It has a low power consumption and the source can be modulated extremely fast.

EMIRS50 are packaged in compact TO-46 cans and are available with protective cap or with reflector; Sapphire or BaF2 windows are optional. 

Axetris IR sources are ideally suited for compact gas detection modules. 

Typical measurement methods are:

  • Non-dispersive infrared spectroscopy (NDIR)
  • Photo acoustic infrared spectroscopy (PAS)
  • Attenuated-total-reflectance - spectroscopy (ATR)

Axetris IR sources have been successfully integrated for many years in various medical, industrial and safety applications. Typical target gases are CO2, refrigerants, CH4, NOX, alcohol and many more.
