IR Spectrum Analyzer Details
Developers in both industry and research use infrared spectrum analyzers for non-invasive characterization of gases, liquids, and solids as well as characterization of light sources. NLIR’s MIDWAVE Spectrometer is a fast, portable, and versatile tool for measuring mid-infrared light in the 2.0 – 5.0 μm range. Designed for applications requiring high-speed and accurate spectral measurements, it captures full spectra in milliseconds, making it ideal for both industry and laboratory.
NLIR’s MIDWAVE Spectrometer has a high sensitivity of 5 pW/nm, and the full-spectrum readout rate of 400 Hz! The spectrometer enables the characterization of light sources and measuring spectral content from chemical processes with a temporal resolution of 10 µs.
High-Speed Fiber-Coupled Design
Our infrared spectrum analyzer connects directly via mid-IR fiber, providing flexible sampling for material characterization, optical coating analysis, gas and liquid phase monitoring, as well as characterization of light sources.
With millisecond acquisition times, it delivers the world’s fastest fiber-coupled MIR spectroscopy. Collect light from remote sampling points, harsh environments, research and development labs, or moving production lines — and analyze it instantly.
MIDWAVE Spectrometer comes with an NLIzeR Software for easy spectral analysis.

Experience real-time measurements
NLIR’s IR Spectrum Analyzer powers measurements of various samples and applications in real time. Explore our measurement examples below.
Multi-Gas Live Monitoring with NLIR'S Infrared Spectrum Analyzer
Gases can be detected using infrared (IR) spectroscopy by measuring light in transmission. A light source sends light through a gas-filled chamber or pipe, and a spectrometer captures how the light is absorbed by the gas.
The video demonstrates this setup in action. NLIR’s FIBER Light Source delivers light through a fiber to a simple gas cell, while another fiber guides the transmitted light to NLIR’s MIDWAVE Spectrometer. The spectrometer captures spectra every 20 milliseconds, clearly showing the transmission features on screen.
Optical Coating Transmission Measurements with IR Spectrum Analyzer
In this video, we demonstrate how NLIR’s MIDWAVE Spectrometer, combined with FIBER Light Source, can measure transmission spectra of optical filters in real time. With an exposure time of just 2 ms, the spectrometer captures data from every filter on the rotating wheel during each full rotation.

Versatile characterization enabled by fiber-coupled spectrometer
We use the NLIR’s MIDWAVE Spectrometer for our calibration set-up. We appreciate the versatility of fibre coupling, the fast response of the detector and the ability to work at room temperature. All these aspects help us in the fundamental step of independent characterization of sources and optical elements.
A key device for sensitive, broadband trace gas detection
We are very satisfied with the outstanding performance of the NLIR’s upconvertion spectrometer, offering both superior sensitivity and spectral range. These advantages allowed us to develop a versatile broadband (> 600 cm-1) trace gas sensor for single species as well as fast and stable multi-species detection. It has been a pleasure working with their innovative and skilled technical team.
