StellarNet Raman NIR spectrometers capture at 1064 nm

May 2, 2013
Portable Raman spectrometers utilize InGaAs detectors to capture NIR spectra induced by 1064 nm lasers.

Portable Raman spectrometers utilize InGaAs detectors to capture NIR spectra induced by 1064 nm lasers. Fluorescence interference with the sample is avoided and SpectraWiz software enables identification of liquids, powders, or solids. The Raman-HR-TEC-IG provides 8 cm-1 resolution with a 1024-element PDA detector, and the standard resolution instrument achieves 16 cm-1 and has a 512 PDA.

1064nm Raman NIR Spectrometers

StellarNet has released a series of portable Raman spectrometers that utilize 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 is problematic with 830nm, 785nm, and lower frequency lasers especially with organic materials. Silicon CCD detectors get saturated and bloom preventing Raman spectra from being extracted. Our high resolution model (Raman-HR-TEC-IG) achieves 8cm-1 resolution with 1024 element PDA detector, while our standard resolution instrument achieves 16cm-1 and has a 512 PDA. Both instruments have integrated two-stage TEC (Thermo Electric Coolers), no moving parts, and are permanently aligned for shock-proof durability. SMA-905 optical input to spectrometer allows attachment of Raman probes or fiber optic sample accessories.

As with all StellarNet spectrometers, the instruments are extremely ruggedized and compact for portable lab and field applications. Each has a PC interface via USB2 for power & data, and includes +5VDC adapter for TE cooler with a battery pack option available for TEC. StellarNet offers additional Raman spectrometers and lasers configured for 532 / 647 / 785 / 830nm. Contact a StellarNet sales representative today with your requirements.
