Our Ocean Optics 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. This unit covers the wavelength range 900 - 2200nm.
The unit comes with an optical fiber for bringing light to the spectrometer. Additional gear is avaialble for absorbance, reflection, or emission measurements. Software will be provided that you must download to your PC.
- 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
