StellarNet RED-Wave near infrared spectrometers provide the high sensitivity and resolution over the 900-2300nm wavelength range using InGaAs PDA technology. The units are exceptionally robust and are packaged in small rugged metal enclosures for portable, process, and lab applications.  Compact size (69 x 100 x 150mm) allows easy integration.

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 unit requires external 5V power supply.  The various models below can be configured for OEM and custom configuration. 

The powerful SpectraWiz® 32 bit spectrometer software is provided free of charge with every spectrometer instrument.  For OEM customers, StellarNet includes drivers and customizable software for operation in WinNT /WinME /Win2000 /WinXP/VISTA/Windows 7.

The SWDLL.DLL is the 32 bit SpectraWiz® spectrometer driver for use with popular Windows software such as Borland Delphi, Microsoft C/C++, National Instruments LabView, VisualBasic, and Galactic Industries Grams/32. The software required to interface with these other packages is included free of charge as part of the SpectraWiz® operating software shipped with each unit. 

We have sample demo program source code available free of charge for software development using StellarNet spectrometers.

StellarNet LabVIEW program is a fully functional customizable spectroscopy program. The LabVIEW programming environment allows rapid customization to adapt the software to any application. Current features include setting of all instrument configuration parameters, plotting of spectral data in Scope mode, Absorbance mode, Transmission mode, and even Irradiance mode. In addition, a time series function is built in that enables the user to select independent wavelengths and follow them as a function of time. This time series data can be exported to file and post-processed for kinetic parameters. In addition to the Spectroscopy Suite, basic VIs are available that  allow the user to integrate StellarNet’s spectrometer into their existing LabVIEW application.


StellarNet also offers the customizable StellarNet VBA program for MS Excel that instantly grabs and graphs data from spectro (SWDLL). Setup and run from Excel in absorbance, transmission, or scope mode. With our VBA modules, you can rapidly customize your spectral analysis to meet your unique research requirements. You can integrate this module’s data acquisition capabilities into your existing analytical spreadsheet, thereby enabling acquisition and analysis of spectral data without leaving the Microsoft Excel environment. Create custom reports, calculate and graph absorbance or percent transmission, all at the push of a button. It’s all here and more importantly, it is included free with your StellarNet spectrometer.
