Introduction

The FT-NIR: fibered NIR spectrometer with a spectral range from 900 to 2500 nm

The FT-NIR Rocket is a high-performance system combining high resolution, broad wavelength range and excellent sensitivity. The FT-NIR functioning principle permits to measure over a much broader range than grating spectrometers that are limited to 2100nm. Its outstanding stability in both wavelength and intensity scales makes it an ideal tool for highly reproducible chemometric analysis.In comparison to array-photodiode NIR spectrometers, the single photodiode operation of the FT-NIR ensures no defect pixels, no gain variation among pixels and no dark-current drifts. Also, the device does not suffer from stray-light as grating spectrometers.
