Raman Application Areas

Raman spectroscopy is useful for analyzing molecules without a permanent dipole moment, which does not show up on an IR spectrum. Raman spectroscopy is used to determine bond lengths in non-polar molecules. It is useful for determining the identity of organic and inorganic species in solution, as the Raman transitions for these species are more characteristic than for IR, where the transitions are much more affected by the other species present in the solution. Raman can be used to analyze solid, liquid and gaseous sample components even through glass and plastic containers.

 Pin Pointer
Pinpointer, the "Point-Click" solution designed specifically for quick material identification and verification on the go and for various field deployments.
The PeakSeeker by Raman Systems is our most practical and easy-to-use Raman spectrometer. It is an excellent choice for users who want a full featured Raman spectrometer but have a limited budget.
 PeakSeer Pro
The PeakSeeker Pro represents the state-of-the-art for an accurate, cost-effective and easy-to-use Raman spectrometer. The premier instrument in the Raman Systems line utilizes TE-cooled, high efficiency CCD detector arrays, and is available with either a 532 nm or 785 nm laser.
 RAM-LR Laser
A stabilized diode laser (at 785 nm) provides an ideal narrow linewidth excitation source for Raman spectroscopy using CCD detectors. The laser can be controlled through software and has all the laser Class IIIb safety features.
 RSM Microscoe
The Raman Systems RSM Video Raman Microscope is an upright laboratory microscope that couples to a Raman Systems spectrometer (sold separately). The accessory is supplied with a Reflected Light Illuminator and a USB Color Video Camera.
 MSK Microscopy Kit
The MSK Raman Microscopy Kit from Raman Systems turns an upright laboratory microscope into a video Raman spectroscope. The kit includes a Raman Beamsplitter Module that mounts below the eyepiece assembly and a USB Color Video Camera that mounts above the eyepiece.
