Metal mirrors can be larger with lower inertia than a comparable glass
mirror. Aluminum is used for a low cost approach and Beryllium is used for
the best performance.
Our 3" mirror has an aluminum mirror substrate which is replicated for a
1/4th wave peak to valley flatness. The replication process is similar to
the process used to make gratings, however the master is an optical flat.
After replication the substrate is coated with either protected aluminum, gold
or silver.
 Modern DSP chips have made it possible to achieve the performance and
resolution of an analog controller with the added benefit of simpler performance
optimization. With a digital controller, the fast steering mirror can be
optimized for its given application.
Our standard fast steering mirrors come with analog controllers that
have user adjustable PID values. The user can easily adjust the controller
for the best response for his application. Currently we are developing a
digital controller for our standard products.
