Abstract
A Raman spectroscopy probe includes a lens tube and an objective lens positioned in the lens tube. The lens tube and the objective lens are composed of microwave transparent materials. A Raman spectroscopy system includes the Raman spectroscopy probe, a microwave reactor having a microwave reactor chamber, a susceptor crucible positioned in the microwave reactor chamber, and a sample crucible positioned in the susceptor crucible. An end of the lens tube is configured to be positioned in the microwave reactor chamber to face an opening of the sample crucible. The Raman spectroscopy system can further include an optics assembly.

A method of operating a Raman spectroscopy system, the method comprising:
- positioning a susceptor crucible in a microwave reactor chamber;
- positioning a sample crucible in the susceptor crucible;
- positioning a Raman spectroscopy probe comprising a lens tube and an objective lens positioned in the lens tube, wherein the lens tube and the objective lens comprise microwave transparent materials and positioning the Raman spectroscopy probe comprises positioning the Raman spectroscopy probe through a microwave field-blocking access port into the microwave reactor chamber, thereby positioning an end of the lens tube in the microwave reactor chamber to face an opening of the sample crucible;
- contacting a laser beam with a sample in the sample crucible, thereby producing Raman scattering;
- and
- collecting the Raman scattering using the Raman spectroscopy probe.
