3D Printable Raman Probe

My 2nd attempt using Blender, this time I was able to integrate Luxrender 1.6.0 as an addon, so now I can render images using a lot more fancy materials and controls :) This is draft V 01.0C for the 3D printed Raman Probe assembly, and I also included a platform I built custom made just for this probe.

A little "dirty" in some spots but that's only because I'm still learning how to use the program :) 

So, I finally figured out Blender ( the latest version 2.79,) I was wrestling with it for a week, using a simple .stl file my Re-focusing lens mount as my object and this is how it came out...

Of course it's not gonna be blue but it just looked so pretty I couldn't resist :) 

Well this is the final component, my master piece, a <1mm beam divergent laser collimation tube assembly, totally 3D printed! I will put up the prototype of the original one I was using after I post this, because I didn't want to take it apart (really for obvious reasons as you will see,) but this collimation tube has a focal distance of 88mm, (hence the same length of the Raman probe).

The next panel image shows a transparency rendering depicting the inner workings of the assembly:

When I have some time, I will construct a build post to put in the build section of this project page.

This is the fiber optic coupler port that connects the fiber cable coming from the Raman probe to the spectrometer. The port also has a coupler on the inner backing to  re-focus the incoming beam to it's proper divergence.

Measurements are: 51mm from re-focusing lens to reflecting mirror, 61.77mm from centerline on reflecting mirror to diffraction grating, 51mm from diffraction grating to centerline on DSLR camera lens.

This is the CAD program I use to build all my 3D parts FreeCad V16, this is the rough draft version, I think I'll have to construct a guide rail system for the rear fiber optic coupler because alignment of the laser line must be 100% perfect as it relates to the fiber optic end point. 

Even though I have built in the diaphragm laser line guide, I still need a way to make final adjustments at this end.

I will have the blueprint draft drawings up soon when I have the final version finished.
