Cavity super optics installation went smoothly.

The input and output 1550 couplers have been installed in the filter cavity (T2300191-M1-SN01  and T2300191-M1-SN02). https://wiki.mccullerlab.com/DCC/S2400001 has been updated accordingly. Note that the super optic mirrors of type "M1" do not have serial numbers printed on the cases like the rest of the types (M2, M3, and M4 do). The M1 mirrors have labels on the cases they were pulled from and on the 1'' inch spacer attached to the flexture mount on the cavity. Rough alignment of the beam is done. Tomorrow we should be able to install the final optic to complete the cavity and search for a beam in transmission.
