The STR250 Laser Raman
Spectrometer is a highly compact, and flexible system with a high
sensitivity to measure an weak Raman scattering from different materials.The
system consists of an imaging spectrometer and TE cooled CCD camera.
We offer a remote probe head for remote sampling, a optical microscope
for small sample with spatial resolution <1micron, and dual excitation
lasers for visible and Near IR region. Near IR laser will resolve
the florescence problem from the organic compound. The system include
user friendly Windows based control and data processing software.

| Raman spectroscopy is the most extensively
used technique for characterizing carbon related materials,
especially CVD diamond, because it clearly distinguishes between
different forms of carbon, viz. cubic diamond, lonsdaleite,
graphite, diamond like carbon and glassy carbon. The main
reason for its extensive use in assessing the quality of diamond
films might be that the Raman scattering coefficient are significantly
higher for the graphitic carbon than the diamond phase. Thus
it is an important tool in estimating the purity of the films.
The right spectrum illustrates how nicely curve fitting can
be performed using Grams/32, advanced data processing software. |
