I've been working feverishly toward getting raman spectra for the past couple weeks...  I updated and have gotten the spectrometer to a pretty good point...and now, tonight have gotten the kinks worked out of the filter wheel assembly and the beam splitter assembly..!  

The beam splitter assembly now has a access port cover to which the beam splitter mount attaches.. The splitter is captured in a small mount that bolts to the bottom of the access port cover..  It allows the beam splitter to be mounted and then fit into the splitter assembly where you can make any minor adjustments needed..  

Here's an exploded view of the beam splitter assembly....

And here is an assembled view...

The filter wheel only needed the wheel itself and the mounting brackets updated...

Here's the new wheel with brackets...

The wheel and brackets just finished printing and I'll get images up as soon as possible... The beam splitter is just starting its print..  Hopefully I can get pictures of that up tomorrow!  Once these are done and assembled, and the splitter and filters are mounted... I should be able to start some testing to get raman spectra!
