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.
