The IS-Instruments dispersive spectrometer is a sleek and efficient instrument designed to be used in a variety of spectroscopic and analytical measurements. It works well with fiber-coupled Raman probes, hollow-core microstructured fibers, and tailored optical setups, allowing for the examination of solids, liquids, and gases in research, lab, and industrial settings.
Its versatile construction permits use in applications ranging from process tracking and material profiling to tritium measurement, hydrogen isotope evaluation, and multi-component gas measurement.
This spectrometer was designed to deliver reliable, high-resolution spectral analysis across a broad range of applications. Built for installation in industrial, research, and laboratory settings, it pairs sturdy optical operation alongside compact, fiber-coupled versatility.
When used alongside conventional Raman probes, this system enables the spectroscopic analysis of both solid and liquid samples for various laboratory and process uses. Coupled with the holloc core microstructured fiber technology developed by IS-Instruments, this platform serves as the foundation for the Notus gas Raman system aimed at sophisticated gas analysis tasks, including tracking hydrogen isotopes and detecting tritium.
