The VIS-NIR-FIB fibered spectrometers
Ultra-broadband spectral range: 350-2600

Our VIS-NIR-FIB are ultra-broadband spectrometers designed for use with fibered probes over the complete VIS & NIR spectral range, 350-2600nm. The system incorporates one Arcoptix FT-NIR Fourier-Transform scanning spectrometer for the NIR range 900-2600 and one multichannel grating spectrometer for the VIS (350-1000nm). Both instruments are integrated in a single, portable housing that has two separate SMA inputs for the VIS and for the NIR ranges, matching the transmission ranges of high-OH and low-OH fibers. The software supplied with the spectrometer automatically merges the spectra produced by the 2 spectrometers.

Unlike most scanning spectrometers used for such applications that take several minutes for a complete scan, the  VIS-NIR-FIB (350-2600nm) give a result within two seconds! The software can be customized on demand for specific colorimetric or other standard measurements. Please contact us for more information: info@arcoptix.com

Main charactiorisic Smaller Spetral range, Better SNR in the VIS range (350-1000nm)

Larger spectral range. Reduced SNR in the VIS Range (up to 5x lower in the 800-1000nm range) dur to grating efficiency. Not recommended if UV is not absolutely necessary.

Efficiencies of VIS and UV-VIS spectrometer gratings

The VIS-NIR-FIB (350-2600nm) and the UV-VIS-NIR-FIB (200-2500nm) not only differ by their spectral ranges, but also by the efficiency of their grating in the VIS or UV-VIS spectral range. The VIS-NIR-FIB offers a better efficiency the range 350-1000nm, while the UV-VIS is ratehr optimized for the UV but has lower performance in the VIS range. if UV is not needed, we recommend strongly to choose the VIS-NIR-FIB spectrometer option which gives much better better results in particular in 700-1100nm spectral region.

Features and benefits
Fibered spectrometer with the broadest available spectrum 350-2600nm

The VIS-NIR-FIB (350-2600nm) are the fiber-input spectrometers covering the broadest spectral range on the market.

Best of two worlds

The use of an Fourier-transform spectrometer for the NIR and a grating spectrometer for the UV and VIS is the best solution for a fast and reliable broadband spectrophotometer.:

  • For the UV-VIS range the most performant solution is the multichannel dispersive spectrometer with a Si-diode array. This solution offers fast measurement times, high sensitivity and good resolution at a moderate cost.

  • For the NIR spectral range, the scanning Fourier-transform spectrometers produced by Arcoptix are superior to photodiode-array based grating spectrometers. Indeed dispersive spectrometers are based InGaAs photodiode arrays that suffer from various noises and distortions due to the pixel variability and usually cannot reach wavelegnths beyond 2300nm.
Free software

The VIS-NIR-FIB (350-2600nm) are delivered with a free Windows compatible graphical user interface (GUI) program. The software automatically merges the spectral data from the VIS and NIR spectrometers.

The free basic software package allows the user to:

  • Configure hardware measurement parameters (amplifier gain, averaging, ...)
  • Display real-time spectral measurement results
  • Set reference spectra (white, dark) and choose among raw spectra, transmission or absorption modes.
  • Usual features such as save, open, zoom, rescale...
  • Save data of combined VIS-NIR spectra, or individual VIS and NIR spectra
Accessories

The VIS-NIR-FIB (350-2600nm) are compatible with many fiber-based accessories available on the market. Attention must be paid to the fact that the spectral range of the accessories covers the full VIS-NIR (or UV-VIS-NIR) spectrum. The illustrations below show two typical arrangement for measuring in diffuse reflectance and in transmission modes with theVIS-NIR (350-2600nm)

Transmission mode

The ARCspectro VIS-NIR-FIB is the ideal spectrometer for measuring the transmission of samples all over the VIS to NIR range. Accessories needed for this configuration are:

  • (1) one Vis-NIR or UV-VIS-NIR llight source, typically a halogen or deuterium + halogen light source (e.g. an ARCLIGHT-NIR or DH-MINI)
  • (2) one Vis-NIR or UV-VIS-NIR fiber patch cable (e.g. our FIB-UVN-600-050)
  • (3) one Vis-NIR or UV-VIS-NIR cuvette holder (e.g. CUV-UV) with UV-compatible cuvette made of quartz glass
  • (4) one Y-branched fiber bundle with 1x UV-VIS and 6x Vis-NIR 200μm core diameter fibers
Reflection mode

The VIS-NIR can also be used for reflection measurements, e.g. using a fibered reflection probe. Accessories needed for this configuration are:

  • (1) one Vis-NIR light source, typically halogen light source such as our ARCLIGHT-NIR
  • (2) one Y-branched fiber bundle with 7x VIS-NIR, 600μm core diameter fibers
  • (3) one Y-branched fiber bundle with 1x UV-VIS and 6x Vis-NIR 200μm core diameter fibers
  • (4) if needed, one diffuse reflectance standard (not shown)
  • (5) if needed, a reflection probe holder/stand (not shown)
