15-mm MMDM with 17 actuators and integrated tip-tilt stage has been specially designed for correction of low-order aberrrations. The deformable mirror has the actuator geometry optimized for the correction of the low-order aberrations, with 12 actuators located outside of the working aperture of 10 mm, and is mounted on a piezoelectric tip-tilt stage. This allows to avoid the double use of the pupil-conjugated plane and to build compact and simple adaptive optical systems.

This is probably the most popular deformable mirror ever made. In production since 1997, hundreds of these devices are used by scientists and engineers in all kinds of adaptive optics project, including laser beam control, real time atmospheric correction, ophthalmology, intracavity laser control, communications, holographic memory, optical fiber switching, etc. Properties of these mirrors are described in numerous scientific publications. Available with Al and gold coatings as standard, custom orders for protected silver and multilayer laser coatings available.
