One option for the mount is a commercial PZT-based tip-tilt mirror, such as the type used in the iLIGO beam line readout system. However, these units have some disadvantages: their range is small (in order of a few milliradians); in our experience they are not very robust; they offer no vibration isolation. Given these downsides, we decided to develop our own mount instead. The design concept for these is something between the Newport Fast-Steering Mirror and the iLIGO small-optics suspension (SOS). The design, called a tip-tilt mount, has been developed and tested at ANU, and is being implemented on the eLIGO OMC beamline.
