NIRQuest 512-1.9 Near Infrared Spectrometer 900-1900nm by Ocean Insight


NIR Spectrometer, 1100-1900 nm, 512-element InGaAs array; includes grating NIR3 (900-1700 nm), CGA-1000 Filter, and SLIT-25


The Ocean Insight (aka Ocean Optics) NIRQuest 512-1.9 near infrared spectrometer covering the 900 – 1900 nm range.

The Nirquest 512-1.9 is a small footprint, fiber optic USB spectrometer that features a cooled InGaAs 512 element detector array for spectroscopic measurements in the 900 – 1900nm wavelength region. The 25 micron slit yields optical resolutions on the order of 5nm FWHM. This spectrometer includes OceanView software and power supplies. We also offer a NIRQuest 512 near infrared spectrometer that covers 900-1700 nm.

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

Excellent for NIR reflectance (add our light source, probe and white standard)

Excellent for Radiometry (add a fiber, cosine corrector and a calibration lamp)
