NIRQuest+ is the next generation of NIR spectrometers from Ocean Optics. The NIRQuest+ family has an improved optical bench design for higher-sensitivity performance and is available in a configuration well suited for your NIR application. NIRQuest+ is available in three versions covering different wavelengths from 900-2450 nm. These spectrometers are ideal for applications including moisture content for fruit sorting; plastics recycling; and chemical concentration measurements. The spectrometer can be used in the lab or on the line, such as on a conveyor belt or in a sample stream.
NIRQuest+ can measure very small changes in absorbed signal, which are typical of harmonic overtones in the NIR. Its higher sensitivity enables better measurement accuracy, particularly in low light onditions. Also, at longer wavelengths, NIRQuest+ measures diffuse reflection at low noise levels, resulting in cleaner spectra at wavelengths where distinct spectral features can be difficult to capture.
For NIR solutions for customer integration projects, Ocean Optics offers several capabilities: in-house feasibility and verification testing via Ocean Lab Services; skilled engineering support for OEM level optimization of spectrometer optics and accessories; and machine learning algorithm development for advanced data identification and quantification.

• High sensitivity: Enhanced optical bench and aperture design for greatly improved spectrometer response, allowing lower limits of detection (LOD).
• Low LOD: Detect weaker sources of NIR light and use shorter integration times to capture necessary spectra.
• Thermal stability: Thermoelectric cooling to -20 °C for low dark current performance Flexible applications: ideal for moisture content of fruits and grains; identification of plastics in recycling; and chemical concentration measurements.
