FT-NIR Rocket

Portable Fibered FTNIR Spectrometer

Stock Status: In Stock


If you are looking for high performance, compact and affordable NIR spectrometer, the ARCoptix FT-NIR Rocket is the instrument that you need. Thanks to its permanently aligned interferometer and solid-state reference laser, the FT-NIR Rocket offers excellent stability in both intensity and wavelength scales. The FT-NIR Rocket is compatible with light sources and sampling accessories typically used with array-detector based NIR spectrometers.

The FT-NIR Rocket is a high-performance system combining high resolution, broad wavelegnth range and excellent sensitivity. Its outstanding stability in both wavelength and intensity scales make it an ideal tool for highly reproducible chemometrics 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-ligtht as grating spectrometers. Finally, all these these advantages come at a very attractive pricing! Contact to ACTTR Technology right away!
