I had to build a far more stable apparatus for holding my laser when illuminating the samples in the cuvette holder in the spectrometer, so keeping my goals in mind, ( low cost but with high precision and quality,) I used my lab stand as a base foundation, since it is made out of metal and has sufficient weight.

Next, I had an old microscope aperture focusing mount and utilized some spare telescope parts and came up with this little baby!

I've already tested it and it's precision is oh, so welcomed! The movement from ascending to descension is extremely smooth, and allows me now to control the fluorescent intensity within the sample in order to eliminate as much signal to noise ratio from the analyte as possible.
