Stability of the micromachined membrane deformable mirror as a freeform optical element

Micromachined membrane deformable mirror (MMDM) can serve as an "ad hoc" free-form optical element. To test the repeatability and stability of the standard MMDM, we have conducted the test of surface figure during multiple thermal cycling, test of …
