How does NLIR revolutionize MIR Spectroscopy?
Mid-infrared spectroscopy offers powerful, non-destructive testing capabilities across industries, enabling precise analysis of liquids, solids, and gases. However, efficiently delivering light to and from the sample while maintaining a safe and practical distance from production infrastructure remains a challenge. Fiber-coupled spectrometers overcome this by providing unparalleled flexibility—allowing critical optical components to be positioned securely, even in complex industrial setups. This versatility makes them ideal for on-site measurements in demanding environments, where space, safety, and practicality are essential.
At NLIR, we’ve reimagined mid-infrared measurements with our patented upconversion technology. By converting mid-IR light into the visible spectrum, our spectrometers deliver faster, more sensitive results—at room temperature—without the noise or inefficiencies of traditional systems. By combining fiber-coupling technology with high sensitivity and speed, our spectrometers ensure reliable and user-friendly solutions for a variety of applications, from quality control in manufacturing to advanced research and development.
What Is an Optical Fiber Spectrometer?
An optical fiber spectrometer uses optical fibers to collect and analyze light, making it convenient for a wide range of spectroscopy applications. Mid-infrared (mid-IR) wavelengths in particular, are critical for understanding chemical compositions, material properties, and more.
What makes NLIR’s optical fiber spectrometers unique is the technology behind them. Instead of relying on conventional mid-IR detectors— which can be slow, noisy, and require cooling — our systems use patented upconversion technology to shift mid-IR light into the visible range. This allows us to take advantage of high-performance visible-light detectors that are faster, more efficient, and exceptionally sensitive.
Why Mid-Infrared Spectroscopy with Optical Fiber Spectrometers Matters
Mid-IR spectroscopy is one of the most powerful tools for analyzing materials at the molecular level. It works by targeting the unique vibrational fingerprints of molecules, allowing for precise identification and measurement of chemical compounds. When combined with optical fiber spectrometers, this technique becomes even more versatile, enabling fast, flexible, and accurate measurements in places where traditional systems fall short.
The Advantages of Mid-IR with Optical Fibers
- Molecular Fingerprint Analysis
Mid-IR wavelengths—spanning from 2.0 to 12.0 µm—provide unmatched detail when it comes to identifying molecules. This range allows you to see exactly what’s in a sample by measuring how its molecular bonds interact with infrared light. It’s especially effective for:
- Detecting organic compounds.
- Monitoring chemical purity.
- Analyzing polymers, coatings, and thin films.
- Non-Invasive and In-line Measurements
Optical fiber spectrometers can take measurements directly at the source, whether it’s on a production line, inside a reactor, or in a remote environment. There’s no need to disturb the sample or deal with complicated setups. This flexibility is particularly valuable for inline monitoring or real-world applications where portability matters. - Reliable in Harsh Conditions
Optical fibers are both compact and flexible. Whether you’re measuring in a vibrational production line, varying temperatures, or need a portable solution, the setup remains stable. This is a huge advantage over bulky, lab-bound systems that can’t handle real-world demands. - Real-Time Feedback
Time is often critical, especially in production processes or fast-moving experiments. Our optical fiber spectrometers deliver spectral data in milliseconds. With acquisition rates of up to 130 kHz, you get instant insights to adjust processes or validate results without delays.
Why NLIR’s Optical Fiber Spectrometers Stand Out
At NLIR, we’ve taken the advantages of Mid-IR spectroscopy and made it faster, more sensitive, and easier to use.
1. A Smarter Approach with Upconversion Technology
Traditional mid-infrared detectors are slow, noisy, and require cooling to function properly. NLIR solves these problems with our patented upconversion technology. Instead of detecting mid-infrared light directly, we shift it into the visible spectrum, where highly efficient visible-light detectors take over.
The result?
- Higher Sensitivity: Detect even the faintest signals, down to a few pW/nm.
- Faster Speeds: Capture full spectra in milliseconds for real-time analysis.
- Simplified Operation: No cooling systems, no added complexity.
2. Compact and Flexible Design
We know every setup is different. That’s why NLIR’s optical fiber spectrometers are designed to fit seamlessly into both lab and industrial environments. The combination of compact size and flexible optical fibers means you can measure where it matters—without moving or disturbing the sample.
- Inline Monitoring: Integrate into production lines for continuous quality control.
- Field-Ready: Portable and robust for offsite measurements.
3. Proven Reliability in Demanding Applications
NLIR’s optical fiber spectrometers are built for real-world performance. Whether you’re monitoring a delicate coating process, analyzing combustion efficiency, or identifying trace gases in the field, our systems deliver reliable results every time.
Here’s where they shine:
- Industrial Quality Control: Real-time monitoring of coatings, semiconductor production, and thin films.
- Environmental Monitoring: Track emissions, detect pollutants, and analyze air quality.
- Advanced Research: Study materials, surfaces, and chemical reactions with precision.
A Smarter Way to Measure Mid-IR
Mid-infrared spectroscopy has always been powerful, but with NLIR’s optical fiber spectrometers, it’s also fast, flexible, and easy to integrate. Whether you’re working at a production line, in a research lab, or out in the field, our systems make high-performance mid-infrared measurements more accessible than ever.
