Near infrared spectrometers

/ Spectrometers

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]

Contact an applications Scientist for help in customizing your NIrQuest configuration.

Each NIRQuest spectrometer model is preset with optical bench and grating options appropriate for many NIR applications. However, we also offer a full range of slit, filter and grating options to optimize your setup for higher resolution needs or other similar performance requirements.

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.
