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]

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.
