Thomas and I Replaced silver coated mirrors with the dielectric mirrors, changed the filter lenses for the Hartmann sensors, and changed the mount for two of the beam splitters that had clipping issues. I aligned the new optics roughly to the old beam path and used a temporary mirror in front of the periscope mirrors to check the back reflection. Currently the periscope is aligned to, roughly, the center of the first in-vacuum lens. Gerardo and I removed the Lexan guillotines from the viewports as well. Once the cables are attached we should be ready to begin alignment to in-vacuum targets.

Happy holidays and good luck vacuum crew.
