The FT-NIR Rocket near infrared (NIR) Spectrometer

Compact Fourier Transform Spectrometer (FTIR) for near infrared spectroscopy. 

fourier transform spectrometerThe FT-NIR Rocket is a fibered scanning Fourier Transform Spectrometer (FTIR) sensitive in the NIR range from 0.9-2.6 or 0.9-1.7 µm, optionally snesntivity can be go down to 600nm. This new fibered FTIR module combines robustness with compact design. This new generation of NIR spectrometers is based on a self-compensated interferometer and has a build-in solid state stbilized reference laser to assure reproductible results in wavelength. The input inteface is a SMA fiber connector which makes the spectrometer compatible with other standard SMA accessories.

The FTNIR Rocket is an ideal product for reproducible chemiometrical analysis due to its high wavelength and intensity stability. The FTNIR Rocket's single photo-diode detection not only allows for attractive pricing, but also guarantees that gain fluctuation, dark current fluctuations, and defect pixels will not be present. Unlike grating spectrometers, this device will not suffer from second or third order ghost spectral contributions.

An Infrared version of the FTIR-Rocket is also offered here.

Additionally, Arcoptix is proud to offer the ArcSpectroHT-NIR: a unique static Fourier Transform spectrometer with no moving parts which is ideal for analysing diffusing parts. For more information please click here.

How does it work?

FTIR spectrometer The FTIR-Rocket uses a self-compensated pendulum Interferometer.This means that off-axis movements created by vibrations or temperature variations of the mirrors are compensated for by the two arms of the interferometer. The optical path difference, used to calculate the spectra, is now unaffected by these vibrations. Thus the architecture of this FTIR system makes the system far less sensitive to vibrations or temperature variations. A solid state temperature-controlled laser is coupled into the interferometer to control the movement of the mirrors. These telecom lasers are more cost-effective, compact and less demanding in maintenance than their classic HeNe laser counterparts.

NIR spectrometer The FT-NIR Rocket has a SMA connector for a fibered light input and is ideal for making fibered measurement setups. Standard grating spectrometer accessories (cuvette holder, halogen lamp or reflections probes) can be used with this product. Ideally the spectrometer should be connected with 0.6mm core diameter NIR fibers. For most uses, a 10-20W halogen lamp light source is sufficient.

Applications:

  • Environmental monitoring
  • NIR and MIR Pulsed LASER measurements (see application notes)
  • Solar cell characterization (see application notes)
  • Security and defense
  • Cosmetics
  • Gas detection (see application notes)
  • Agriculture
  • Food, beverage & dairy
  • Plastics
  • Process control (Chemical monitoring, Pharmaceutical manufacturing, Solar cells characterization)
  • Textile
  • And much more...

 

 

 


Features and benefits

Attractive pricing:

More cost-effective solutions are possible now than ever before because the FT-NIR Rocket makes use of a few small optical elements based on a relatively low-cost technology. 

Self compensated Interferometer principle:

  • Solid state laser control makes device compact and reduces maintenance costs. No high voltage driving as for He Ne lasers.
  • Alignment of the device is simple and robust.
  • The multipass self compensated interferometer presents an optimal configuration for miniaturization
  • Thanks to its symmetry the interferometer remains stable with temperature variations and vibrations.

Optional parameter:

Variable gain and resolution permit to optimize measurement parameters.

USB Infrared lamp:

IR spectrometer

The Arcoptix USB lamp is a compact USB-powered lamp. The USB lamp features a SMA 905 connector for easy coupling in optical fibers. Via these fibers, the lamp can be connected to a reflection probe, an integration sphere, or a reflection probe.

Additionally, the USB lamp features a smart power control for high lamp stability, a mechanical variable shutter for power output control and an integrated cuvette or filter holder. Since this lamp is USB-powered, it is ideal for on-the-field spectral measurements.

This USB lamp is available in two versions: one optimized for VIS-NIR, and a version for the MIR region:
