Tested and fully functional. Cosmetic imperfections are present but do not affect performance. Verified operational with both 1310 nm and 1550 nm laser sources, producing clean, well-defined spectral peaks at each wavelength. Fitted with standard Grating NIR2 for the 900–2200 nm range.

Included in the sale:
• Ocean Optics NIRQuest NQ512-2.2 spectrometer
• USB Serial Cable
• Power Adapter (25 W)

The Ocean Optics (Ocean Insight) NIRQuest512-2.2 is a scientific-grade, small-footprint fibre-optic near-infrared spectrometer designed for demanding NIR spectroscopy applications in the 900–2200 nm wavelength range. It features a high-stability Hamamatsu G9206-512W 512-element InGaAs linear array detector mounted on a high-performance f/4 crossed Czerny-Turner optical bench with low-noise electronics. Deep two-stage thermoelectric cooling reduces dark current and stabilises the detector, making the instrument well suited to applications such as moisture content analysis in food and beverages, pharmaceutical QA/QC, chemical identification, polymer and hydrocarbon analysis, tunable laser wavelength characterisation, and optical fibre characterisation.
