Recent Progress on Correcting Components (useful for ELTs) at CILAS
Recent progresses on correcting components at CILAS are exposed: the first one is relative to
a 3.5 mm spacing, 28x28 order demonstrator for small pitch concave or convex deformable mirrors
designed, manufactured and tested in the scope of feasibility study for the E-ELT MCAO module.
The second one is relative to a 1 mm spacing, 50x50 order deformable mirror prototype. This
prototyping allows the validation of some main important steps of manufacturing very high order
deformable mirrors. This new piezo array family called “miniDM” uses transverse
piezo-electrical effect. The last one is relative to a Tip/Tilt Mount prototype that has been
designed and manufactured for the Narrow Field Infrared Adaptive Optics System (NFIRAOS), which
is the MCAO system of the TMT. The system shows large angular stroke and bandwidth while
supporting a heavy deformable mirror
