     RED-Wave-NIRX-SR InGaAs Miniature NIR Spectrometers 

RED-Wave-NIRX-SR Models
Range 900-2300nm
StellarNet’s high performance InGaAs extended range spectrometers cover the NIR wavelength range from 0.9-2.3μm in one unit. The spectrometers are exceptionally robust with no moving parts and are packaged in small rugged metal enclosure (2.75” x 4” x 6”) for portable, processes, and lab applications. The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25μm by 250μm tall to provide best signal performance. The detector has an integrated two-stage thermo electric cooler (TEC) maintained at –20 °C, stabilized within +/-0.1°C. The RED-Wave-NIRX-SR-InGaAs spectrometers use single strand SMA 905 fiber optic input.

InGaAs 512 pixels spectrum showing spectral characteristics of Tylenol, Excedrin PM, and Ibuprofen tablets. Often NIR spectroscopy is used as a non-contact method to distinguish between coatings.


Dual System Configurations
All NIRX-SR units can be coupled with StellarNet’s BLACK-Comet or UVN-SR units to cover the entire 200-2300nm range. Coupling the units can provide you with quick analysis of color in the visible spectrum and additionally compound analysis though compound fingerprint identification in the near infrared spectrum.

NIR applications include chemical ID and moisture analysis, SpectroRadiometry and optical power measurements, laser characterization, microsensor applications, and thicker thin-film measurements.

Optional Configurations
Several units may be daisy chained via a parallel cable or USB-2 hub allowing simple configurations for dual and multi-beam process applications.  


Free SpectraWiz Software
The powerful SpectraWiz® 32 bit spectrometer software is provided free of charge with every spectrometer instrument.  This includes drivers and customizable software for operation on Win95 / Win98 / WinNT / WinME / Win2000 /WinXP.    The SpectraWiz software is considered the "Swiss Army Knife of Spectroscopy and may be used to accurately measure wavelength emissions, reflectance, transmission, absorption, concentrations, and absolute intensities.  In addition to real-time spectroscopy,  SpectraWiz® has built-in applications for SpectroRadiometry, SpectroColorimetry, ChemWiz chemistry lab concentration analyzer, and UV level monitors.

Interface
The system includes a high speed plug & play interface using USB-2 connection.
