Ocean Optics launches compact NIR spectrometer

The NIRQuest512-2.2 is a high-performance unit with response from 900nm to 2,200nm.

It uses a high-stability, 512-element Hamamatsu Indium Gallium Arsenide (InGaAs) array detector in a compact optical bench with a two-stage thermoelectric cooler and low-noise electronics.

Depending on the configuration - half a dozen grating options and five sizes of optical bench entrance slits are available - optical resolution of ~0.5 nm to 5.0nm (FWHM) is possible.

Higher-resolution setups are said to be particularly 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 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 an existing Wi-Fi connection.

With the addition of the NIRQuest512-2.2, the company now offers NIR spectrometer options with spectral response from 900nm to 1,700nm, 900nm to 2,050nm, 900nm to 2,200nm and 900nm to 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 and process control.
