Si-MIR AirTrace

Si-MIR AirTrace is a mid-infrared spectral sensing device designed for field experimentation with miniaturized FT-IR gas sensing technology in open or ambient environments.

Its architecture provides access to the fundamental MIR absorption bands, allowing researchers to observe and analyze multiple gases simultaneously. Unknown gas species can be investigated without hardware changes.

Calibration models can be updated to refine detection targets, making Si-MIR AirTrace a practical tool for feasibility studies and defining requirements for future gas-sensing systems.
