     RED-Wave NIR InGaAs Portable NIR Spectrometers

RED-Wave NIR InGaAs Models
Range 900-2300nm
StellarNets’ high performance InGaAs spectrometers cover the NIR wavelength range from 0.9-2.3 μm.  The units are exceptionally robust with no moving parts and are packaged in small rugged metal enclosures (2.75” x 4” x 6”) for portable, process, and lab applications.  The InGaAs detector is a Sensors Unlimited linear photo diode array with 512 pixels (1024 optional) 25μm by 500μm tall to provide maximum sensitivity. The detector has an integrated thermo electric cooler (TEC) maintained at –10 °C, stabilized within +/-0.1 °C.  The RED-Wave-NIR-InGaAs spectrometers use single strand SMA 905 fiber optic input.  Several models provide a variety of operational ranges and resolutions suitable for both spectroscopy and optical spectrum analysis-

Extended Range
Extended range systems for 900-2300nm are available in 512 or 1024 element InGaAs PDA’s with 25 x 250um tall pixels. Because of reduced sensitivity and higher dark noise, the extended range InGaAs spectrometers are primarily used for measuring tunable lasers, characterizing optics, or chemical absorption & transmission thru cuvettes, flow cells, and dip probes.

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® spectrometer software is provided free of charge with every spectrometer instrument.  This includes drivers and customizable software for Windows.  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.
