NIR Spectrometers

Leverage Ocean spectrometers for NIR measurements, tapping into a feature-rich spectral response to gain insights into subsurface sample characteristics. 

High Sensitivity and Low Noise

Ocean NR Series spectrometers are engineered for high-performance spectral analysis, delivering exceptional precision and reliability. Designed to excel in complex and low-light environments, NR spectrometers offer optical resolution as fine as 2.85 nm FWHM for detailed peak discrimination.

Thermoelectric cooling ensures thermal stability and consistent results, while High Gain configurations enhance sensitivity to detect even the faintest signals. Whether you’re analyzing low-concentration samples or working in challenging conditions, NR spectrometers provide the clarity and confidence you need.

Frequently Asked Questions

What is Near-Infrared (NIR) Spectroscopy and what is it used for?

Near-infrared (NIR) spectroscopy is an advanced analytical technique that measures light in the 900–2500 nm range.

NIR spectrometers are used for rapid, non-destructive analysis of chemical and physical properties such as moisture content, fat and protein levels, polymer identification, and overall material composition.

NIR analysis is widely used across industries for quality control, process monitoring, and material verification.

Which NIR spectroscopy wavelength range should I choose?

  • 900–1700 nm: Ideal for moisture and organic overtone bands; offers lower cost and reduced complexity, making it suitable for routine food quality testing and moisture analysis in agriculture.
  • 900–2200 nm: Provides additional chemical specificity through more combination bands; excellent for pharmaceutical analysis or distinguishing between similar polymers in recycling operations.
  • 900–2500 nm: Delivers the broadest coverage for maximum compound identification and robust model development, valuable for biotechnology, medical diagnostics, and advanced industrial applications.

Choosing the right wavelength range depends on your specific application, desired chemical specificity, and budget.

What industries use NIR spectrometers?

  • Pharmaceuticals & Biotechnology: Identify counterfeit drugs, measure active ingredient concentration, and monitor fermentation processes.
  • Food & Agriculture: Assess protein in grains, measure fat in dairy, or check moisture in produce to ensure consistent food quality.
  • Environment & Sustainability: Detect environmental contaminants and support sustainable resource management.
  • Semiconductor & Polymers: Verify polymer identity, monitor semiconductor wafer quality, and support material sorting for recycling.
