FT-IR Rocket
Fibered Fourier-Transform Infrared Spectrometer

The FT-IR "Rocket" is a robust, small-footprint, lightweight and high performance FT-IR spectrometer. The FT-IR Rocket can be used in a fiber connected version or a free space version. The device is very useful for IR measurements that needs fiber coupling or any other special arrangements like for IR light source characterization.
FT-IR "Rocket" offers high resolution and sensitivity thanks to the use of thermoelectrically cooled MCT (Mercury-Cadmium-Telluride) detectors. Its permanentely aligned interferometer and its solid-state reference laser ensure that the highest performance is delivered at every scan. The system has high stability in both wavelength and intensity scales, making it an ideal tool for highly reproducible chemiometrical analysis. The FT-MIR and FT-IR are also used by many of our customers for characterizing infrared lasers, who are using is an an Optical Spectrum Analyzer (OSA).

Standard models of the FTIR-Rocket

FT-MIR Rocket 2-6μm

FT-IR Rocket 2-12μm

The FT Rocket infrared spectrometer is proposed in 2 standard versions: The FT-MIR 2 - 6μm, FT-MIR 1.5 - 8.5μm and the FT-IR 2 - 12μm. Both offer a resolution of 4cm-1. The main differences lie in the beamsplitter material (CaF2 or ZnSe) and the sensitivity of the detector: the narrower band 2-6μm detector has a much better sensitivity. On request we can fit the detector to your needs.

Wavelength resolution

The resolution of Fourier-transform spectrometers is usually given in wavenumbers (ν), which are the inverse of wavelength (ν=1/λ). The conversion betwen wavenumber resolution and wavelength resolution is Δλ = λ2 · Δν and is shown in the graph below:
