The NIRQuest+2.2 from Ocean Insight is a Near-Infrared Spectrometer that operates at a wavelength of 900 nm - 2200 nm. It has an optical resolution from 3.4 nm to 10.8 nm (at FWHM) and entrance slit of 25 µm. This spectrometer has a signal-to-noise ratio of up to 13000:1 and an integration time of 1 ms - 200 ms. It has an RMS dark noise of 16 counts (at 10 ms), 24 counts (at 30 ms), 6 counts (at 100 ms), and 12 counts (at 250 ms).
The NIRQuest+2.2 has three gratings and an InGaAs linear array detector. This spectrometer has an OF1-RG830 longpass NIR order sorting filter that transmits wavelength above 830 nm and SMA 905 input fiber connector. It is available in a module that measures 182 (L) mm x 110 (W) mm x 47 (H) mm and is ideal for applications such as characterization of materials, identification of plastics in recycling, and measurement of chemical concentration of liquids.
