NIR Spectrometers

High Sensitivity and Low Noise

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

Discover New Ocean NR Spectrometers

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.
