Micromachined Membrane Deformable Mirrors
MMDM are small and light, especially compared to continuous faceplate piezoelectric mirrors
Negligible power consumption
High optical quality, better than 400 nm rms over the whole aperture
Very smooth surface: the scattering is negligible
Large correction range - up to 25 µm in total wavefront deformation
These mirrors can be coated with metal and metal-dielectric coatings: to be used in lasers at power levels of up to 600 W CW
Zero hysteresis
Negligible parameter drift

Micromachined membrane deformable mirrors with apertures in the range of 10 to 50 mm represent a high-quality affordable solution for fast dynamic correction of low-order optical aberrations such as defocus, astigmatism, coma, etc in lasers, telescopes, ophthalmology, displays and general imaging optics.
