Item Code: NIRQUEST512

The NIRQuest512 is a versatile spectrometer with optimum response at 1600 nm and optical resolution of 3.0 nm FWHM. NIRQuest512 cover the wavelength range from 900-1700 nm and is especially useful for NIR applications ranging from moisture detection and chemical analysis to high-resolution laser and optical fiber characterization.

NIRQuest512 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. 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.

  • Robust – deep thermoelectric cooling down to -20 °C for low dark current
  • Fast – great for applications with chemometric models
  • Modular – configurable with a range of light sources, fibers, accessories for your specific application
