NIRQuest 光谱仪

If you utilize NIR spectroscopy for research, process or diagnostics, NIRQuest is a less costly, less complex alternative to FT-IR and comparable technologies.

NIRQuest delivers a high-performance optical bench with low-noise electronics and more grating options than we've ever offered.

This compact, multi-interface spectrometer is available in version for 900-1700 nm, 900-2050 nm, 900-2200 nm and 900-2500 nm.

NIRQuest's modular design delivers more customization for a wider variety of applications including medical diagnostics, pharmaceuticals analysis, environmental monitoring and process control.

NIRQuest for Laser Analysis
NIRQuest is versatile enough to be configured for high-resolution laser and optical fiber characterization. The NIRQuest delivers reliable optical resolution to <0.25 nm (FWHM) and is easily customized for your high-resolution spectral applications.

Turn NIRQuest into a Network Spectrometer
When purchased with the Remora Network Adapter users can communicate with the NIRQuest over Ethernet or Wi-Fi. Use with SpectraSuite Software, and turn your device into a network accessible spectrometer. Remotely capture spectral data from anywhere Plus, Remora allows multiple users to access data and experiment settings without the need for additional equipment. Remora's web-interface works with all popular web browsers and allows you to monitor data from a PDA, iPhone, and most internet ready devices. - Learn more

¹ Useable range?is defined in the context of the NIRQuest models 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 C. 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.
