Raman Spectrometers
StellarNet has released a new series of updated spectrometers configured for Raman spectroscopy applications that perform quick identification of a variety of liquid, solid, or powder samples.

StellarNet Raman spectrometers include enhanced CCD array detectors for 785nm Raman (other wavelengths available on request) or cooled 1024 element InGaAs photodiode arrays for 1064nm Raman where interference from sample fluorescence is minimized and virtually non-existent.  1064nm Raman Press Release

As always with StellarNet instrumentation, the fiber optically coupled Raman spectrometer series is extremely ruggedized and compact for portable and field applications.  USB2 connection to PC for power and data is quick and easy! 

• Our Raman spectrometers are ruggedized miniature
spectrometers configured specifically for Raman
spectroscopy applications using 785nm lasers.

• Enhanced optics allow for extreme sensitivity and extra
low stray light values down to 0.05%.

• High Resolution models available down to 4 cm^-1 with
options for maintaining S/N with TEC cooling.

• Compact size & seriously Rugged for portable and field
applications. Metal enclosures are extremely durable.


Pharmaceutical Match Test- Raman-HR spectra of Tylenol (Acetaminophen/Paracetamol) displaying Library search hit of Tylenol as #1 and Excedrin (containing Acetaminophen/Paracetamol) as #2.


Raw Material ID of Maltol-
The Raman-HR Spectrometer is used to capture the Raman spectrum of a powdered Maltol sample in a 1/2" vial using the Ramulaser and Raman probe.  StellarNet's free SpectraWiz software performs a Library search displaying Maltol as the #1 hit. Maltol is a naturally occuring organic compound primarily used as a sweetener and a flavor enhancer.

Raman of Impurities in Lubricants
1064nm Raman spectra of pure lubricant, lubricant with impurity, and impurity with identifiable Raman peaks showing feasibility of qualitative & quantitative analysis of impurity.

Raman Spectrometer Features
• Low cost - Ruggedized - High performance

• Shock proof - Permanently aligned optics

• Standard Fiber interface to Raman probes

• SpectraWiz Software and SDK included Free

• Simple USB2 interface to Netbook & PC’s

• Suitable for lab, process, or field applications

The StellarNet Raman-SR and Raman-HR spectrometers are standard and high resolution models achieving 8cm^-1 and 4cm^-1 resolution respectively using CCD detector arrays.  For 1064nm Raman an InGaAs detector is installed in the Raman-HR-TEC to cool the detector.

These Raman spectrometers have 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.  Contact a StellarNet sales representative today for more details and your requirements at other laser frequencies used for Raman such as 532 / 647 /830nm.

Free SpectraWiz Software- Library Search
The powerful SpectraWiz® spectrometer software is provided free of charge with every Raman spectrometer instrument.  In addition to real-time spectroscopy,  SpectraWiz® has built-in applications for SpectroRadiometry, SpectroColorimetry, ChemWiz chemistry lab concentration analyzer, and UV level monitors. For Raman Material ID applications StellarNet has added a new Raman Library Search function. Users can capture their Raman spectra and search and search a their database for hits and matches. 


1064nm Raman of Rum with Methanol Impurity-
Raman spectra of Rum with methanol spike using the Raman- Probe-1064, Ramulaser-1064, and Raman-SR-TEC-IG spectrometer. The probe is held directly up to the side of the Rum bottle.  Comparison with pure methanol shows similar peaks and means for detection.



Raman of Polyatomic Inorganic Anions-
Sodium dihydrogen phosphate (NaH₂PO₄) and Disodium hydrogen phosphate (Na₂HPO₄) can be dissolved in water and distinguished by 785nm Raman spectroscopy.
