“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 ship with a 2
nd
-order filter. See an
Applications Scientist for details.
4
Optical resolution (FWHM) depends on grating and slit selection.
5
SNR will decrease at longer integration times.
6
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.
