At NLIR, we empower industrial innovators with our cutting-edge mid-infrared measurement technology. Through OEM collaborations, we can co-develop customized sensing solutions that would integrate seamlessly into your products, processes, or platforms.
Whether you’re building advanced process analyzers, smart inspection tools, or embedded diagnostic systems – our team is ready to design a mid-IR spectroscopy module (spectrometer or wavelength converter) tailored to your technical and commercial needs. From rapid prototyping to scalable production, we offer long-term partnerships that match your roadmap and performance requirements.
In this video, NLIR’s MIDWAVE Spectrometer with FIBER Light Source measures optical filter transmission in real time. With just 2 ms exposure, it records every filter on the rotating wheel in each full turn. You’ll first see the distinct spectra of each filter, then how the system keeps capturing accurate data even as the wheel spins at 300 RPM — giving less than 30 ms per filter, similar to conveyor belt speeds.

No cryogenic cooling needed – simplifying integration and reducing total system cost
Together with our OEM partners, we turn complex challenges into high-performance solutions. Our compact, high-speed mid-infrared spectrometers integrate seamlessly into your systems, delivering real-time, full-spectrum insight that drives quality, speed, and innovation in demanding industrial environments.
NLIR’s 2.0 – 5.0 µm spectrometer delivers rapid, high-resolution infrared measurements that integrate seamlessly into OEM optical systems. Its speed enables real-time process feedback for applications such as:
OEM partners can embed this capability into coating analysis tools, chemical composition trackers, or optical coating process monitors to improve yield and reduce cycle time. The compact, robust design allows easy integration without complex cooling or alignment, enabling precise, continuous monitoring in demanding production environments.
NLIR spectrometers provide fast, multi-component gas and emission monitoring in challenging combustion environments. With full-spectrum mid-IR analysis, OEMs can integrate real-time exhaust and flame diagnostics into:
This enables tighter process control, better emission monitoring, and improved efficiency. One compact device can replace multiple single-gas sensors, capturing rapid changes in combustion chemistry and supporting both industrial and research applications, including advanced combustion studies.
With powerful chemical selectivity in the mid-IR, NLIR spectrometers identify plastics, powders, pharmaceuticals, minerals, textiles, and more in milliseconds. OEMs can integrate this into sorting, inspection, or process-control systems to detect and quantify materials where NIR or RGB imaging falls short. Applications range:
The rugged design supports high-throughput, accurate material control even in harsh production environments.
NLIR spectrometers enable OEMs to design remote sensing systems for detecting and characterizing gases or thermal signatures from distant objects. Mid-IR’s strong molecular absorption bands allow simultaneous monitoring of multiple gases for leak detection, environmental compliance, or industrial safety.
The technology also detects subtle variations in thermal emissions for applications such as:
High-speed, high-selectivity performance gives OEM systems a decisive advantage in challenging environments.
NLIR’s 2.0 – 5.0 µm spectrometer enables OEMs to scan and verify coatings, layers, and surface treatments with full spectral accuracy. Real-time feedback ensures coating thickness, curing state, and uniformity meet exacting standards. Applications include
High-speed, high-selectivity measurements allow OEMs to detect defects instantly, reducing waste and improving product quality.
The NLIR spectrometer measures spectra in only milliseconds. 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.
NLIR’s spectrometers use detector arrays with 2048 pixels, so the resolution can be as low as 2.5 cm⁻¹ in a wide optical bandwidth.
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.
