NIRQuest 512-2.2 Near Infrared Spectrometer 900-2200nm by Ocean Insight


NIR Spectrometer, 900-2200 nm, 512-element InGaAs array; includes grating NIR2 (900-2200nm) and SLIT-25


The Ocean Insight (aka Ocean Optics) NIRQuest512-2.2 spectrometer covers the 900 – 2200nm range.

Presidents Choice!  This NIRQuest 512-2.2 NIR spectrometer is our favorite NIRQuest unit, great range, great sensitivity, best value.

Small footprint fiber optic, USB spectrometer features a cooled enhanced InGaAs 512 element detector array for spectroscopic measurements in the 900 – 2200nm wavelength region. The 25 micron slit yields optical resolutions on the order of 5nm FWHM  power supplies.

Robust– deep thermoelectric cooling down to -20 °C for low dark current

Fast – great for applications with chemometric models

Modular – configurable with a range of light sources, fibers, accessories for your specific application
