Dual DSR Models
Range 200-2300nm
StellarNet Dual-DSR spectrometer systems combine two instruments to cover the ultra violet, visible and near infrared portions of the electromagnetic spectrum.  The two instruments work as one creating a unified spectral graph over the entire wavelength region, 200-2300nm.  The two instruments employ both a UV-VIS detector array and NIR-InGaAs array in order to cover the entire range. 2048 element UV-VIS detector with the option of 512 or 1024 elements in the NIR.  Various models allow for ranges from 200-1700, 280-1700, or 200-2300nm depending in the measurement specifications required.  Like always StellarNet spectrometers are ruggedized for field or lab process measurements. A Miniature USB-Hub provides instrument PC interface.  The Dual-DSR system has many applications for spectroradiometry, food and drug QA/QC, and chemical process measurements due to its ability to probe the near infrared while simultaneously measuring sample UV and color spectrum.

These units are extremely ruggedized.  The detector is bolted in position and military grade epoxy holds the concave grating in place, making the instruments vibration tolerant, durable, and suitable for just about any lab and/or field measurement. A multi-band filter is integrated into the spectrograph to provide order sorting and prevent optical aliasing. The instruments optical input is attached via standard SMA-905 connector, using single strand fiber optic cable with typical silica core diameters of 400um, 600um, 1000um.


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.
