We have placed a number of mirrors on the H1 PSL table to divert the beam after the periscope to the FI testing and alignment area. This was done by:
a) moving three 1" IO_AB mirrors from their intended to new temporary positions
b) placing three 2" mirrors from the eLIGO POY and POB on the table.
The full setup will also require an HWP to control the polarization of the beam sent into the FI, and (maybe) a lens to get the correct beam size at the location of the FI.

Note: the schematic diagram below does not properly identify the identities of the newly placed/moved mirrors, only their positions.
