In this work we report on a fabrication method for producing large-area multilayer polymer membranes and describe its
application to the instrumentation of a deformable mirror. This implementation allows for highly flexible mirrors in
which mechanical properties vary in a controlled manner in order to better match optical requirements. In addition, the
mechanical properties of such membranes allow for a large number of closely spaced actuators. We report on the
mechanical properties of metal-polymer membranes and discuss their application to pulse shaping experiments.
