Some more updates:

  • The "random mirror" is said to be a super mirror by Frank. It is some sort of splitter, so not interesting to me. I labeled it (mounted) and put it on the top right optics shelf.
  • Frank helped me out with another REO supermirror. It had some dust on it, so I blew it off. I did not wipe it; it looked clean.
  • I measured the 532 transmission to be 56 and 58% for the two mirrors, so I will use these to separate my light.
  • I adjusted my mode matching so that I had a 400 um (width) spot at my green PDs (no extra lenses!).
  • I am using some lenses to get the right spot size for my ISS PDs.
  • Pictures/Diagrams soon!
