This is my prototype laser Collimation tube for this spectrometer, this piece was very difficult to make with the precision that I had to make it in, but I did it. This is section (1) the initial data results using this design, very good results by the way! Section II will have the blueprints on how I made it, I just didn't want to take it back apart to take internal pics because it would have been too much of a problem to put it back together.

I will present those pictures and drawings in my next project log and how to assemble it.
