First Raman Spectra

Description

These are not done with the Horiba Aramis Labram. 
They were done using separate optics and the Science-Surplus spectrometer
using this setup.

JM Derochette suggested some high Raman scattering minerals for 
633nm and for making system adjustments easier: 
Potassium dichromate (lopezite), crocoite, and sulphur. 

Here are some low-resolution results using a Science-surplus spectrometer, 
a 632.8 line filter (OPT-IF-633) and a 643LP filter using a setup that was less-sophisticated than
Radagast's "Lego Raman" method.

Note: the scale is labeled "Wavelength (nm)" which is the default for the "Spectrum Studio" software
provide by Science-Surplus, but the scale is actually showing the Raman shift in Kaysers (wavenumbers, cm^-1).
I might shift the spectrum window further towards the Stokes side later.
