I finally got enough money and time together to have these optical couplers fabricated out of aluminum. I had intended to make them out of 304SS, but the cost of fabrication was a little more than double. I did a quick search of the usability of aluminum in a vacuum, and I figure that I'm good to 10^-6, which is very much lower than my lowest operating pressure 10^-3.
