Dispersive Spectrometer
Our dispersive spectrometer has been developed to deliver reliable, high-resolution spectral analysis across a wide range of applications. Designed for integration into laboratory, industrial, and research environments, the system combines robust optical performance with compact, fibre-coupled flexibility.
When combined with standard Raman probes, the system supports spectroscopic interrogation of solids and liquids for laboratory and process applications. Integrated with IS-Instruments’ holloc core microstructured fibre technology, the platform forms the basis of the Notus gas Raman system for advanced gas analysis applications. This includes hydrogen isotope monitoring and tritium sensing.
