Ocean Optics - NIRQuest Spectrometer

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]

Make NIRQuest Your Own

512-element InGaAs array detector options covering 900-1700 nm and 900-2200 nm. 256-element options covering 900-2050 nm and 900-2500 nm
Wide range of grating and optical bench options to optimize your setup
External hardware triggering function for capturing data when an external event occurs; or to trigger an event after data acquisition

Meet the Lineup
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.

See the full specification chart here.

NIRQuest512
	Perfect if you need best response at ~1600 nm and optical resolution of ~3.0 nm (FWHM)
NIRQuest512-2.2
	If you require good response across 900-2200 nm without sacrificing optical resolution performance (~4.6 nm)
NIRQuest512-2.5
	If you require good response across 900-2550 nm without sacrificing optical resolution performance (~4.1 nm)
NIRQuest256-2.1
	For good response at higher wavelengths (~1900 nm) and if high optical resolution (~7.6 nm) is not a major consideration
NIRQuest256-2.5
.......	You require good response at higher wavelengths (peak response is at ~2200 nm) and if high optical resolution (~9.5 nm) is not a major factor

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) Prices begin at under $500.

Add an Annual Service Package to your NIRQuest for only $800 and receive annual spectrometer wavelength recalibration and complete system maintenance.

Light Sources and Accessories
The LS-1 and HL-2000 Tungsten Halogen Light Sources are our best broadband light source options for your NIRQuest spectrometer.

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.

The OF1-RG830 is an optional longpass filter that is installed in the optical bench and transmits signal >830 nm. The OF1-RG830 is most useful for NIRQuest512 applications where second-order effects may be a concern. Ask an Ocean Optics Applications Scientist for the details.

Turn NIRQuest into a Network Spectrometer
When purchased with the Remora Network Adapter, you can communicate with the NIRQuest over Ethernet or Wi-Fi. Turn your NIRQuest into a network accessible spectrometer, remotely capture spectral data from anywhere and allow multiple users to access data and experiment settings without the need for additional equipment.

¹ “Useable range” is defined in the context of the NIRQuest model’s detector response and its typical grating response. For example, the 512-element detector has response at 850 nm, but grating response begins at 900 nm. The G9206 256-element detector response is sensitive to TEC temperature, and has response only to 2050 nm when the TEC is set to -20 ºC. The G9208 256-element detector has response to 2550 nm, but the grating efficiency drops off at 2500 nm.

² Other filter options are available for order-sorting in the NIRQuest256-2.1 and NIRQuest256-2.5. Please contact an Applications Scientist for details.

³ Optical resolution (FWHM) depends on grating and slit selection.

⁴ SNR will decrease at longer integration times.

⁵ Maximum integration times are defined as the longest amount of time one can integrate the spectrometer before the dark level rises to half of full scale.
