multiSense: QCL based spectrometer module for gas analyzers
multiSense is a QCL based spectrometer module for gas analyzers manufacturers. It combines the unique properties of mid-infrared lasers together with the compactness and affordability of photoacoustic detection. In 1 dL, our offer can detect up to 10 gases, such as: CO, CO2, NO, NO2, NO, SO2, SO3, HS, NH3, CH4… as well as more complex molecules such as hydrocarbides or blood constituents.
mirSense has reached an unprecedented level of co-integration of quantum cascade lasers and photoacoustic detection in order to deliver such an innovative module. Working together with CEA-Léti, we also benefit from the best of the silicon industry to provide this cost effective approach.
Off-the-shelf components are available and mirSense is able to provide “design to cost” components for large volume (>100 000) applications when both performance and cost matter !
