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 within and outside the lab.
NLIR’s MIDWAVE Spectrometer has high sensitivity of -80 dBm/nm or better, 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 time resolution of 10 µs.
pOWERED BY NLIzeR Software
MIDWAVE Spectrometer comes with an NLIzeR Software for easy spectral analysis. With NLIzeR, you get:
- Adjustable exposure time, averaging, gain, and offset.
- Live data stream, external trigger mode, background capture, transmission view, data saving, and many more features.
API interfaces for MATLAB, Python, and C (via DLLs), enabling seamless integration into custom workflows or automated processes.

Combustion Process Measurements in Real Time with NLIR's IR Spectrum Analyzer
The MIDWAVE Spectrometer captures light and generates infrared spectra seamlessly with minimal delay. As shown in the video, the measured spectra are updated in real time. The spectral features visible originate from warm water and carbon dioxide in the flame. The exposure time for this measurement is 5 ms.
Optical Coating and Thin Film Measurements with MID-Infrared Spectrum Analyzer
The MIDWAVE Spectrometer is ideal for fast transmission measurements of optical coatings, thin films on wafers, and plastic foils. The video demonstrates several transmission measurements performed with a 20 ms exposure time. The live data readout is clearly visible on the computer screen.
Measure reflection from (almost) any sample with IR Spectrum Analyzer
The MIDWAVE Spectrometer is also very useful for reflection measurements due to its high sensitivity. The video demonstrates several reflection measurements on various materials using our TOUCH Interface.
Despite the sample’s curvature, the data displayed on the screen is of exceptional quality, thanks to the sophisticated internal design of the TOUCH Interface and the high sensitivity of NLIR’s MIDWAVE Spectrometer.
Measuring liquid content with a mid-infrared fiber probe
By combining NLIR’s MIDWAVE Spectrometer with the FIBER Light Source, you can achieve fast and accurate measurements in the 2.0 – 5.0 µm wavelength range, enabling real-time monitoring of liquid content. The fiber-coupled ATR probe from ArtPhotonics offers high transmission and integrates seamlessly with our products.

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.
