Ocean Optics (Dunedin, FL) has added another option to its nearinfrared spectrometer line: the NIRQuest512-1.9. The high-resolution device features a response from 1100-1900nm. The product includes a high-stability, 512-element Hamamatsu Indium Gallium Arsenide (In- GaAs)-array detector, and it is available with multiple grating and optical bench options for optimizing performance between 1100-1900nm. The standard NIRQuest512-1.9 comes with a 150 lines/mm grating, 25 micron entrance slit, and a non-fluorescing longpass filter that transmits >1000nm.
NIRQuest512-1.9 has external hardware triggering functions that allow users to capture data when an external event occurs, or to trigger an event after data acquisition. Spectrometer operation is controlled using SpectraSuite software, a modular, Java-based spectroscopy platform.
The low dark noise characteristics of the NIRQuest make it possible to integrate the spectrometer (or expose the detector in the spectrometer to light) for longer durations. Signal to noise ratio at full signal is >15000:1 at 100 millisecond integration time. High gain mode operation is available for applications where sensitivity is paramount.
