Non-dispersive IR-spectroscopy in harsh environments

Inhalt:
The global climate change calls for a more environmental friendly use of energy and has led to stricter limits for the emissions of various greenhouse gases. Consequently, there is nowadays an increasing need for the detection of exhaust and natural gases. This need leads to an ever-growing market for gas sensors, which at the moment is dominated by chemical sensors. Yet, the increasing demands to also measure under harsh environmental conditions pave the way for non-invasive measurements and thus to optical detection techniques. Here, we present the development of a nondispersive infrared absorption spectroscopy (NDIR) method for application to optical detection systems which can operate under harsh environments.
