Ocean Optics has added another option to its small-footprint near-infrared (NIR) spectrometer line with the NIRQuest512-1.9. The spectrometer is a high-resolution device with response from 1,100 to 1,900 nm and is suited for applications ranging from monitoring changes in chemical processing to characterizing lasers for semiconductor assembly and medical treatment.

The NIR spectrometer has a high-stability, 512-element Hamamatsu indium gallium arsenide (InGaAs)-array detector and is available with multiple grating and optical bench options. The standard spectrometer comes with a 150 lines/nm grating, 25-micron entrance slit, and a non-fluorescing longpass filter that transmits greater than 1,000 nm. The filter helps to mitigate second-order effects.

The NIRQuest512-1.9 has external hardware triggering functions that allow users to capture data when an external even occurs, or to trigger an event after data acquisition. Spectrometer operation is controlled using SpectraSuite software, a modular, Java-based spectroscopy platform.
