Yend Pcal in-vacuum periscope final optical alignment
Craig Conley, Doug Cook, Travis Sadecki, Rick Savage

Today we used a 1047 nm alignment laser to assess the as-installed alignment of the Pcal periscope optics for the Pcal paths.

We didn't yet verify the alignment of the ETM camera  view optics because the viewports for those paths have not yet been installed.  This will hopefully be completed next week.

The alignment looks very good.  One mirror on the upper beam path required a slight adjustment, but otherwise everything was well-aligned as found.

Note that the first contact has been removed from both sides of both Pcal windows on the A1 adapter (thank you Margot).

We transitioned back to Laser Safe.

We removed the YLF alignment laser and we are closing the work permit.

The four pairs of special 1 micron-only laser glasses are being returned to the LSB Optics Lab.

The work permit for this task has been closed (signed off).

Thanks to JustinB for all the assistance with the temporary SOP.
