Ocean Optics of Dunedin,FL,USA has added another option to its small-footprint near-infrared spectrometer line with the NIRQuest512-1.9,a high-resolution device with response from 1100nm to 1900nm suiting applications including characterizing lasers for semiconductor assembly and medical treatment.
The NIRQuest512-1.9 incorporates a high-stability,512-element Hamamatsu indium gallium arsenide(InGaAs)-array detector and is available with multiple grating and optical bench options for optimizing performance between 1100nm and 1900nm.The standard NIRQuest512-1.9 comes with a 150 lines/mm grating,25 micron entrance slit and a non-fluorescing long-pass filter that transmits>1000nm(helping to mitigate second-order effects).
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,which is useful in low-light-level environments.Signal-to-noise ratio at full signal is>15000:1 at 100ms integration time.High-gain-mode operation is available for applications where sensitivity is paramount.
