StellarNet goes viral with InGaAs Raman spectrometers
The firm's latest detectors which use indium gallium arsenide, offer benefits over silicon based detectors which can suffer from saturation and bloom
StellarNet has released a series of portable Raman spectrometers that utilise InGaAs detectors to capture NIR spectra induced by 1064nm lasers.
Sample fluorescence is avoided while the SpectraWiz software enables quick identification of liquids, powders, or solids.

Fluorescence interference can be a problem with 830nm, 785nm and lower frequency lasers especially with organic materials. Silicon CCD detectors get saturated and bloom preventing Raman spectra from being extracted.
Stellarnet's high resolution model (Raman-HR-TEC-IG) achieves 8cm-1 resolution with a 1024 element PDA detector, while its standard resolution instrument achieves 16cm-1 and has a 512 PDA.
Both instruments have integrated 2 stage TEC (Thermo Electric Coolers). These instruments have no moving parts and are permanently aligned for shock-proof durability. SMA-905 optical input to spectrometer allows attachment of Raman probes or fibre optic sample accessories.
StellarNet says its hardy compact spectrometers are suited to both portable lab and field applications. Each has a PC interface via USB2 cable for power and data and includes +5VDC adapter for TEC cooler - battery pack option available for TEC.
