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 and 512-element detector has response to 2550 nm, but the grating efficiency drops off at 2500 nm.

Other filter options are available for order-sorting in the NIRQuest 512-2.5. NIRQuest 512-2.5 ships with a 2
nd
-order filter. See 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.
