Mono 31 Deformable Mirror

Mono 31 Deformable Mirror

CILAS is a pioneer in the field of Adaptive Optics. We have developed and manufactured performant deformable mirrors (Stacked array,Bimorph, Monomorph mirrors) notably for astronomy and laser applications, for more than twenty years. With our experience and our know-how, we have increased the number of actuators, the mirror sensitivity as well as we have improved the optical quality. Our DMs represent a breakthrough in Adaptive Optics and their reliability has been fully demonstrated.

Principle and advantages

CILAS monomorph mirror is a deformable mirror (DM) made of assembly of one plate of piezoelectric material and one glass plate which is polished and coated.

This simple design allows to reduce the usual "print through effect" of DMs which is due to discontinuities (electrodes, actuators...) at the backside of the optical plate. High spatial frequencies on the residual wavefront of the laser beam are minimized. This DM gives and optimal correction of the wavefront distortions without creating energy modulations in the propagation of the laser beam.
