24 Unpacking the FSM
4.3 Storing and Shipping the Mirror Head
When the mirror head is not in use, replace the oval protective cover so that
it covers and protects the mirror. If you ever have to ship the mirror head,
also reposition the lens tape.
4.4 Replacing the Mirror
The FSM is designed so that the user can replace the mirror assembly in the
event that the original mirror has been damaged or different spectral
characteristics are required. FSM mirrors bonded to a metal carrier are
available from Newport as subassemblies. Hex wrenches are required tools
for mirror removal and reinstallation. The FSM-300 requires 0.050” hex
wrenches. Use of Loctite 222 thread locker on mounting screws is
recommended.

To do so, remove the four retaining socket head cap screws using the
appropriate hex wrench. Then remove the mirror carrier. To do so, remove
the four retaining socket head cap screws using the appropriate hex wrench.
Reverse the process to install the new mirror carrier. Application of Loctite
222 thread locker to each of the mounting screws is recommended.
CAUTION
The mirror surface is extremely delicate. Wear latex gloves to
minimize the possibility of fingerprints. Be extremely careful not
to scratch the mirror surface with the wrench or cap screws.
