The ARCspectro MIR and NIR Spectrometer
A miniature Fourier Transform Spectrometer (FTS) based on innovative micro-mechanical technology for NIR spectroscopy.
Product description
The ARCspectro-NIR (MIR) is a family of scanning Fourier Transform Spectrometer (FTS) using an exclusive actuator fabricated thanks to modern micro-mechanical technologies. This actuator enables precise and fast scans with one single detector. As a result, the ARCspectro-ANIR does not need expensive NIR photo-diode array.
The ARCspectro-ANIR products family has intrinsically no wavelength range limitations. The device can is modulable and can be adapted to any wavelength range in the NIR and the MIR. The Arcspectro-ANIR shows a high wavelength and intensity stability which makes the device suitable for reproducible chemiometrical analysis. Also the single photo-diode detection assures no defect pixels, no gain fluctuation and no dark current fluctuations and allows attractive pricing. Also the device does not suffer from second or third order ghost spectral contributions as grating spectrometers.

The ARCspectro-ANIR products family offers a variety of spectrometers having different detectors type: InGaAs-pin photodiodes for wavelengths up to 2600nm and three stage TE cooled IR photovolataic (Hg,Te, Cd)Zn detectors from Vigo systems . Therefore, we supply a a choice of 3 standard instruments. On request we can fit the detector to your needs.

The ARCspectro ANIR products family uses the so-called Lamellar Grating Interferometer. The Lamellar Grating Interferometer is a grating having a variable depth. Contrary to the Michelson interferometer, which splits the amplitude at the beamsplitter, the Lamellar Grating Interferometer splits the wavefront at the grating and, consequently, does not need a beamsplitter. By using an exclusive micro-mechanical scanning systems, we have been able to build the first truly portable, handheld scanning Fourier Transform Spectrometer, which makes the ARCspectro-ANIR products family unrivaled in its category.
Apart of its particular functioning principle, the ARCspectro ANIR is a typical fibered NIR spectrometer and can be used with the same assecories as for standard fibred grating spectrometer. Cuvette holder or reflection probes from other suppliers can be connected to an halogen lamp and the ARCSpectro-ANIR spectrometer. Ideally the spectrometer should be connected with 0.6mm core NIR fibres for maxiaml troughput of the system. A 10 or 20 W halogen lamp is sufficient for most applications.

Features and benefits
Active laser position control:
Permits to control the scan precisely at every measurements and to enhance reability of the system.Lamellar Grating Interferometer principle:
The lamellar grating interferometer presents an optimal configuration for miniaturization
Contains no transmitive elements such as a beam-splitter for example (necessary in the Michelson interferometer configuration).
The lamellar interferometer is a common path interferometer. This means that the light travelling along the two arms of the interferometer follow almost the same geometrical path which minimizes the impact of environmental fluctuations.
Optional parameter:
Variable gain and resolution permit to optimize measurement parameters.Distinct advantages of the ARCspectro-ANIR
1 single photodiode (no need of CCD):
Single photodiode instead of a CCD line leads to low noise and cost-effective detection solutions, particularly in the NIR. The choice of available detectors is much larger than CCD. In addition, it is much easier to dedicate a detector to specific needs. Also there are no defect pixels no gain fluctuation and no dark current fluctuation (between pixels) as it is generally the case for NIR 2.6 mm CCDs. Also MIR wavelength range (2-4.5 um) can only be measured with a scanning systems.Wide wavelength range combined with high resolution:
Thanks to its operating principle, the ARCspectro-ANIR presents a relatively high resolution combined with a large spectral range. Compared to multichannel NIR grating spectrometers that has only a limited amount of pixels (max. 256 pixels) at disposal (around 15 nm resolution can be obtained)Attractive pricing :
Since the ARCspectro-ANIR does not use very expensive InGaAs photodiode arrays, production prices are somewhat lower than for high resolution grating spectrometers. More cost-effective solutions than ever possible before.
Software
The ARCspectro-ANIR series is delivered with a free windows XP,2000, compatible program.
The software recognize automatically the spectrometer (USB plug and play system) and
is able as other conventional spectrometer software to:
- Display real time spectral measurement results
- Configure measurement parameters (integration time, averaging).
- Choose Transmission or Reflection mode
- Usual features such as save, open, zoom, rescale...
- Some specific features related to Fourier transform spectrometry: choose apodization (automatic recognition option), look and save the interferograms.
On demand application specific features can be implemented in the program within a few weeks. Visit our custom software page.
Also free Labview Vi's for driving the spectrometer are available on demand.
