NIRQuest 2016

The Ocean Optics NIRQuest is a versatile NIR spectrometer for applications ranging from moisture detection and chemical analysis to high-resolution laser and optical fiber characterization. NIRQuest spectrometers cover the wavelength range from 900-2500 nm. This year 2016 Coean Optics have refreshed the NIRQuest with a new replaceable slit design, and an optional internal shutter.

Advantages of the NIRQuest

  • Reliable, robust spectrometer with deep thermoelectric cooling down to -20 °C for low dark current
  • Fast data transfer – great for applications with chemometric models
  • Configurable with a range of detectors, gratings and slits for your specific application

The models are available in two different ways: custom configured and preconfigured.

Custom Configured NIRQuest Series Spectrometers

When you select a custom configured spectrometer, we work with you to design the optimum configuration for your NIR measurement. We assemble the ideal combination of optical bench components, including gratings, slits and filters to deliver the performance your application demands. Our Application Sales Engineers will help you with choosing the correct components, light sources and fiber accessories.
