Nirquest512, 900 - 2500nm Spectrecology

NIRQuest high performance fiber optic NIR spectrometers

 

Our 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 ultra low-noise electronics. The spectrometer comes in 4 versions with InGaAs or enhanced InGaAs detectors sensitive up to 2500nm.

  • Robust – deep thermoelectric cooling down to -20 °C for low dark current
  • Fast – great for online applications, chemometric models that require high s:n
  • Modular – configurable with a range of light sources, fibers, probes and other accessories for your specific application

NirQuest comes in 4 standard models:

  • NIRQuest512, 900-1700nm, ~3.0 nm FWHM
  • Nirquest512-1.9, 900-1900nm, ~3.1nm FWHM
  • NirQuest512-2.2, 900 – 2200nm, ~4.6nm FWHM
  • NirQuest512-2.5, 900 – 2500nm, ~6.3nm FWHM
