Versatile InGaAs-array spectrometer for a host of applications from 900-2500 nm
A high-performance optical bench, low-noise electronics and various wavelength range options make the NIRQuest Spectrometer from Ocean Optics (www.OceanOptics.com) versatile enough for NIR (near infrared) applications ranging from moisture detection and chemical analysis to high-resolution laser and optical fibre characterisation. This robust, plug-and-play spectrometer is available in versions for 900-1700 nm, 900-2050 nm and 900-2500 nm coverage.

NIRQuest uses a high-performance Indium Gallium Arsenide (InGaAs)-array detector in a compact optical bench with thermoelectric cooler and low-noise electronics. A high gain mode option improves system sensitivity for low light-level and low-concentration measurements. In addition, integration times as rapid as 1 ms are possible.
NIRQuest’s modular design and new grating options deliver more customisation for a wider variety of applications: moisture analysis in grains and cereals; chemical analysis of blood and tissue; bacterial detection in food and beverage production; nitrogen content monitoring of plants and soils; and chemical composition of pharmaceuticals. A special grating option and external triggering are useful tools for high-resolution (to 0.25 nm FWHM) laser characterisation. NIRQuest Spectrometers are also available for integration into OEM devices.
The NIRQuest uses SpectraSuite Spectrometer Operating Software – a modular, Java-based spectroscopy platform that operates in Windows, Mac OS and Linux operating systems. Plus, NIRQuest can be bundled with the Remora Network Adaptor from Ocean Optics to turn the system into a multi-user spectral data server over Ethernet or an existing Wi-Fi connection.
