WeChat ServiceARCoptix VIS-NIR-FIB
The ARCoptix VIS-NIR-FIB is an ultra-broadband spectrometer designed for use with fibered probes over the complete VIS & NIR spectral range (350-2500nm). The system incorporates one Arcoptix FT-NIR Fourier-Transform scanning spectrometer (model FTNIR-L1-025-2TE) for the NIR range 900-2500 and one multichannel grating spectrometer for the VIS (350-1000nm). Both instruments are integrated in a single, portable housing that features 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 (350-2500nm) give a result within two seconds! The software can be customized on demand for specific colorimetric or other standard measurements.

Features and benefits
Fibered spectrometer with the broadest available spectrum 350-2500nm
The VIS-NIR-FIB (350-2500nm) is the fiber-input spectrometer 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 VIS is the best solution for a fast and reliable broadband spectrophotometer.:
uFor the 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.
uFor 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.
