Ocean Optics has expanded its offering of small-footprint near-infrared spectrometers with the introduction of NIRQuest512-2.2, a high-performance unit with response from 900-2,200nm. The spectrometer is ideal for applications ranging from moisture detection and chemical analysis to high-resolution laser and optical fibre characterisation.

NIRQuest512-2.2 uses a high-stability, 512-element Hamamatsu Indium Gallium Arsenide (InGaAs)-array detector in a compact optical bench with two-stage thermoelectric cooler and low-noise electronics. Depending on the configuration – a half-dozen grating options and five sizes of optical bench entrance slits are available – optical resolution of ~0.5-5.0nm (FWHM) is possible. Higher-resolution setups are especially useful for characterising lasers.

External hardware triggering functions allow users to capture data when an external event occurs, or to trigger an event after data acquisition. This capability can be especially useful for capturing data from automated processes or from devices such as solar simulators that flash synchronously.

The SpectraSuite Operating Software used by the spectrometer is a modular, Java-based spectroscopy platform that operates in Windows, Mac OS and Linux operating systems. In addition, NIRQuest512-2.2 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.

With the addition of the spectrometer model, Ocean Optics now offers NIR spectrometer options with spectral response from 900-1,700nm, 900-2,050nm, 900-2,200nm and 900-2,500nm. Multiple grating, optical bench and accessory options make it possible to configure a NIRQuest system for a variety of applications in medical diagnostics, food and beverage monitoring, pharmaceuticals analysis, environmental monitoring, process control and more.
