NIRQuest+ NIR Spectrometers

Product catalog summary

Overview
NIRQuest+ spectrometers are designed with an enhanced optical bench for higher sensitivity and are available in three configurations: NIRQuest+1.7 (900-1700 nm), NIRQuest+2.2 (900-2200 nm), and NIRQuest+2.5 (900-2500 nm). These spectrometers are suitable for both laboratory and industrial applications, such as material characterization, plastic identification in recycling, and chemical concentration measurement in liquids.

Key Specifications

Wavelength Range: NIRQuest+1.7: 900-1700 nm, NIRQuest+2.2: 900-2200 nm, NIRQuest+2.5: 900-2500 nm
Optical Resolution: ~3.4-10.8 nm (FWHM) depending on model
Integration Time: 1 ms-200 ms
Signal-to-Noise Ratio (SNR): Up to 15000:1 depending on model
Entrance Aperture (Slit): 25 μm
Thermal Stability: Thermoelectric cooling to -20 °C for low dark current
Order-Sorting: OF1-RG830 longpass filter; transmits >830 nm
Relative Sensitivity Gain: Up to 2.5x versus previous models

Applications

Measurement Speed: Enhanced sensitivity improves SNR performance over shorter integration times, ideal for moving samples on conveyor belts or flowing liquids.
Low Limits of Detection (LOD): Higher sensitivity allows for better measurement accuracy, especially in low light conditions.
Reflection Measurements: At longer wavelengths (up to 2500 nm), higher sensitivity results in cleaner spectra with lower noise levels.

Conclusion
The NIRQuest+ spectrometers offer significant improvements in sensitivity and performance, making them suitable for a wide range of applications where precision and speed are critical.

Catalog excerpts

High-sensitivity Near Infrared Analysis NIRQuest+ spectrometers have an enhanced optical bench design for higher-sensitivity performance and are available in three convenient configurations – NIRQuest+1.7 (900-1700 nm), NIRQuest+2.2 (900-2200 nm) and NIRQuest+2.5 (900-2500 nm). The NIRQuest+ is our flagship NIR spectrometer. NIRQuest+ spectrometers can be used in the lab or on the line, such as on a conveyor belt or in a sample stream. Applications include characterization of materials; identification of plastics in recycling; and measurement of chemical concentration of liquids
