Near-Infrared spectrometers for virtually anything you can imagine

No matter what your work demands, NIRQuest has you covered. NIRQuest is the line of Near-Infrared Spectrometers that deliver superb performance, accuracy and reliability. The NIRQuest series of spectrometers are small-footprint, near- infrared instruments with high-performance response that cover various ranges from 900-2500 nm. Thanks to their low-noise optoelectronics and a range of grating and bench options, NIRQuest spectrometers are ideal for demanding applications ranging from moisture detection and chemical analysis to high-resolution laser and optical fiber characterization. What’s more, NIRQuest spectrometers can be customized for a variety of applications by selecting different gratings, slits and optical bench accessories. [optical Bench options]

High-resolution custom NIR options

Unlike most small-footprint NIr spectrometers, NIrQuest can be optimized for high resolution (<0.25 nm fWHm) analysis. this makes the system especially useful for characterizing lasers and optical fibers as well as analyzing atomic emission lines. Contact an applications Scientist for help in customizing your NIrQuest configuration.

calibration and service

We offer two spectrometer wavelength calibration sources: the ar-1 argon Source (696-1704 nm) and the Xe-1 Xenon Source (916-1894 nm).

Light sources and Accessories

the LS-1 and HL-2000 tungsten Halogen Light Sources are versatile, broadband light source options for your NIrQuest spectrometer. Our coolred light source provides illumination from 1000-5000 nm. Low oH content optical fibers and probes are optimized for response from 400-2100 nm. Look for assemblies with the VIS-NIr designation to ensure best performance with your NIrQuest. Several standard and optional longpass filters are available for different combinations of NIrQuest spectrometers. Of-1-cGa780 (transmits >780 nm), of1-rG830 (longpass NIr filter) and of1-cGa1000 (transmits >1000 nm) are among the options. Operating software for NIrQuest is SpectraSuite (required) and omnidriver is an optional development package available. Software is priced separately. NIrQuest spectrometers are backed by our industry-exclusive 3-Year Warranty. for added protection and annual maintenance, consider an optional aSp-NIr or ttS-NIr Service package.
