Ocean Optics has expanded the capabilities of its small-footprint near-infrared spectrometers with the introduction of NIRQuest512-2.5. A high-resolution device with response from 900-2500 nm, NIRQuest512-2.5 is well suited to laser characterization and applications requiring longer integration times.

A high-stability, 512-element Hamamatsu Indium Gallium Arsenide (InGaAs)-array detector doubles the amount of pixels previously available in the 900-2500 nm range, significantly increasing optical resolution. Depending on the user-selected configuration of grating options and optical bench entrance slit size, optical resolution as good as 4.1 nm-6.3 nm (FWHM) is possible. The lower overall dark noise of the system enables longer integration times, which is especially useful in low light level environments.

Users are able to capture data when an external event occurs, or to trigger an event after data acquisition, with the spectrometer’s external hardware triggering functions. Spectrometer operation is controlled using SpectraSuite software, a modular, Java-based spectroscopy platform. In addition, NIRQuest512-2.5 can be bundled with the Remora Network Adapter from Ocean Optics to turn the system into a multi-user spectral data server over Ethernet or existing Wi-Fi connection.
