What makes NLIR a great portable alternative to FTIR?
NLIR spectrometers offer cutting-edge technology for a faster, more sensitive and vibration-tolerant performance compared to conventional FTIR spectrometers, making our spectrometers ideal for a wide variety of industrial applications. Developers in both industry and research use NLIR’s mid-infrared spectrometers for molecular spectroscopy measurements instead of FTIR devices because of their portable design, ultra-fast spectral acquisition, and room-temperature operation capabilities.
Being a fast, portable, and versatile tool, NLIR’s MIDWAVE Spectrometer is ideal for measurements at the production line. Designed for applications requiring high-speed and accurate spectral measurements in 2.0 – 5.0 µm wavelength range, it captures full spectra in milliseconds, making it ideal for inline, online or atline measurements.
High-Speed, Portable Design
NLIR’s MIDWAVE Spectrometer has has high sensitivity of 5 pW/nm, and the full-spectrum readout rate of 400 Hz! The spectrometer therefore enables the characterization of multiple gases simultaneously, time-resolved emission monitoring, light source characterization, measuring spectral content from chemical processes with a temporal resolution of 10 µs, amongst many other applications requiring real-time monitoring.
With millisecond acquisition times, it delivers the world’s fastest fiber-coupled molecular spectroscopy. Collect light from remote sampling points, harsh environments, or moving production lines – and analyze it instantly.
MIDWAVE Spectrometer comes with a free NLIzeR Software for easy spectral analysis.

Improve your measurement capabilities
Compared to traditional FTIR spectrometers, NLIR’s MIDWAVE Spectrometer offers significant advantages in MIR spectroscopy detection. Whether you need to perform inline, online, or atline measurements, our spectrometer can be well-integrated into your process. Explore a few measurement examples below.
Multi-Gas Live Monitoring with NLIR'S MIDWAVE Spectrometer
The video demonstrates how a light source sends light through a gas-filled chamber, and a spectrometer captures the light absorbed by the gas. 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 NLIR's MID-Infrared Spectrometer
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.
High-Speed plastic foil characterization with MIR Spectrometer
The video demonstrates an example of a spinning sample wheel that rotates at the speed of 300 rounds per minute (RPM). This demonstrates how fast MIDWAVE Spectrometer is able to acquire spectral information of different plastic foils, showing the potential for in-line monitoring.
Measure reflection from (almost) any sample with MIDWAVE Spectrometer
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.
EXPERIENCE OUR BREAKTHROUGH TECHNOLOGY
The NLIR Spectrometers are based on a patented upconversion technology that converts MIR light to near-visible light. The VIS-NIR light can then be detected by silicon-based CMOS detector arrays. This approach brings endless MIR field measurement possibilities at your production line.
Measurement Speed
The NLIR spectrometer measures spectra in only milliseconds, providing faster data collection compared to FTIR spectrometers. The integration time can vary from 100s of ms down to 11 µs depending on the need. The external trigger can be used to capture data at the right time in order to optimize monitoring speed.
Vibration Tolerance
NLIR spectrometers have no moving parts and are therefore tolerant to vibrations, making them suitable for harsh industrial environments.
No cooling needed
By converting mid-infrared light to near-visible light, NLIR spectrometers utilize uncooled silicon-based sensors, eliminating the need for cryocooling systems. This approach mitigates the thermal noise that typically limits infrared measurements, enabling you to conduct a wide range of measurements with ease.
Readout Rate
NLIR’s spectrometers are so fast because they use an array detector that can read out data with 400 Hz and even up to 130 kHz.
Sensitivity
The uncooled NLIR detectors are at least as sensitive as cryocooled detectors but offers superior speed without the complexity and cost of cooling systems. Check out specifications of the MIDWAVE Spectrometer above for more details.
Portability
The absence of cryocooling detectors and fiber-coupled design makes our spectrometer a portable device, which you can bring to a production line to perform various inline, online, or atline measurements at any industrial environment.
